Diamond – April’s Gemstone of Sparkling Glamour

Diamond is a precious gemstone frequently incorporated into some of the most modern, beautiful handmade jewelry in the world. It is a clear stone revered for its ability to reflect light, and is widely recognized as the April Birthstone and the center stone used in most American engagement rings. But beyond its modern-day uses and associations, diamonds hold a decadent mythological, spiritual and etymological history that add nostalgic value to their already strong aesthetic worth. Read on for more information that will help you fall in love with your diamond jewelry – or inspire you to buy some today!

Diamonds are prized for their beauty and durability. A form of carbon, the Diamond is the world’s hardest known natural material. In fact, the word “Diamond” comes from the ancient Greek adamas, which means invincible. Because of their durability, Diamonds have been used in tools for since antiquity. Diamonds were first used as religions icons in India nearly 2,500 years ago. Since then, they’ve become highly coveted gemstones.

Diamonds are often described and valued by their gemological characteristics: The Four C’s (carat, color, cut and clarity). Although Diamonds are used in many types of fine jewelry, they are traditionally associated with engagement and wedding rings. Most people think diamonds are white or colorless. In fact, yellow and brown Diamonds are the most common. Any Diamond with a hue other than brown or yellow is considered a colored Diamond. Colorless Diamonds are pure or nearly pure. The color scale for colorless diamonds goes from D (colorless) to Z (light yellow).

Diamonds look best as parts of formal evening jewelry when paired with Black Onyx, dark amethyst or cool blue sapphire. More casual combinations include lighter, bridal colored blends with aquamarine, pearls and carnelian. To see a selection of handmade artisan jewelry featuring raw diamonds, click here. Diamond is typically considered a sophisticated gemstone that works well with any outfit. In earrings, it works especially well to enhance the luster of blue or green eyes.

Almost half of all Diamonds come from mines in central and southern Africa. The other half comes from mines in Canada, India, Russia, Brazil and Australia. Today, the jewelry industry is buzzing about high-quality or lab-created diamonds. These synthetic diamonds possess the same molecular structure as natural diamonds. With public concerns about the mining industry, these man-made beauties offer a compelling alternative to the real thing.

Mohs’ Hardness score is based on a 10 point scale where 10 is the most resistant, like a diamond, and 1 is easily scratched, such as Talc. Diamonds are often proved real by the fact that they can scratch glass. Because they are such scratch resistant stones, diamonds are extremelty suitable as a component of oft-worn jewelry. Diamonds should be regularly cleaned by a professional or with a soft rag and mild soap and water. Avoid ultra-sonic cleaners, solvents and harsh chemicals when cleaning your handcrafted jewelry as exposure to these elements can damage semi-precious and precious gemstones and pearls.

CZ Jewelry Versus Diamond Jewelry

Honestly, there really is no real contention here, especially if you are literally in love with all kinds of jewelry. Even though some people may not openly express it, we all love that little sparkle, no matter what precious metal it is or what gemstone or mineral it shows off. Cubic zirconia jewelry, diamond jewelry, gold jewelry, silver jewelry … agate, turquoise, pearls … the list plainly goes on and on.

However, some people do find a bit of friction when it comes to the appealing cubic zirconia or cz jewelry and the ever dependable and timeless diamond jewelry. Some assert that both just can’t be of the same level. Although they both somewhat look alike, there has to be one which is, in theory, more superior. Naturally, these are two very different elements; one is naturally made while the other is man-made. So for those of you who cannot make up your minds whether you want cz jewelry or diamond jewelry, here is the full low-down:

CZ Jewelry

CZ jewelry (like diamond jewelry) never really stands alone. You will often see cz rings set on sterling silver jewelry, or a pair of cubic zirconia gems on some sterling silver earrings. CZ is a diamond stimulant, and yes, it is completely man made. This is one of the most important elements of the cubic zirconia that helps bring down the cost of the jewelry made from this material.

CZ can also be engineered in such a way that it is almost indistinguishable from real diamonds. It can look so alike to diamonds that often times only trained gemologists can actually spot the difference. However, one element of the CZ jewelry that makes it so popular among jewelry enthusiasts is its capacity to be engineered to diamond perfection – from the cut of the diamond, to the color, and finally to the clarity of the material.

Diamond Jewelry

We’ve all heard that saying, diamond is a girl’s best friend. Admittedly enough, most still believe that this statement is true. But diamonds and diamond jewelries are far too precious these days. They are definitely too pricey to buy on a whim. And not all of these so-called real diamond jewelries actually carry precious diamond in the first place. In fact, some pieces carry synthetic diamonds which are also known as lab-manufactured diamonds. There are even others which have enhanced diamonds. These pieces are natural diamonds which are enhanced via laser treatments. And yes, the primary concern here is always the price. Truly great diamonds have never been known to have depreciated in value.

Since diamonds are naturally made through a geological process there are a lot of imperfections and impurities associated with them. This is the primary reason why gemologists rank them by carat weight, clarity, color, and cut. More often than not, the diamonds that are within our budget range unfortunately end up being those that fare poorly in ranking.

So when it comes to the ultimate question of CZ jewelry versus diamond jewelry, it all really depends on you and your own preferences. If you are looking for something that looks stunning and just like a real diamond that is actually affordable, then CZ jewelry wins. However there is just something truly special about natural and real diamonds, regardless of their expensive price.

The Cheapest Diamond in the World Ever

We have the most expensive diamond in the world but don’t forget that we can also have the cheapest diamond in the world. So, if it is the cheapest diamond in the world, how much would it be? Can everyone afford to buy one? I can assure you that real diamonds cost a lot of money to buy, but what if there is an alternative to real diamonds? What about man-made diamonds? They look just the same and have the same features, like sparkling brightly when there is light.

Surprisingly, man-made diamonds are as real as the ‘real’ diamonds from a mine. The only difference is that man-made diamonds are made in a factory using the latest technology to compress carbon at a high pressure. As for the real diamonds from the mine, the diamonds are created using the natural process of compression, but it takes millions of years to achieve the same result.

As such, you can get the cheapest diamond in the world if you buy the synthetic diamonds, which is just the same as the real diamonds that cost you a fortune to get but a carat of it. The best part is the man-made diamonds are very much the same as the real diamonds. It is difficult to tell them apart for a common person. Only an expert can separate the real from the fake, but overall it looks just the same and sparkles just the same. Therefore, there is no difference if you are going to buy a man-made diamond ring for your wedding or engagement because, basically, they are the same except the time involved to produce each of them.

There is an increase in man-made diamond production, as there are more and more people looking to own diamonds without having to pay a hefty price. So the Demand for man-made diamond is on the rise. As long as the diamonds are real, they are excellent. Who says it must be originally from a mine, as not only do they cost a fortune but the man-made diamonds are exactly the same.

However, if you are looking for real diamonds at a cheaper price, I would suggest you look for real diamonds with round cut. It is the most popular shape of diamonds used for making bracelets, rings and earrings. Besides, since there are so many round diamonds compared to other shapes of diamonds, it stands to reason that this type would be slightly cheaper.

When it comes to choosing the cheapest diamonds, you must learn the 4C’s rule. The 4C’s are carat, clarity, colour and cut. Carat is a measurement of the diamond’s weight. The more carats mean the diamond is heavier and naturally more expensive. The number of inclusions available determines clarity. The fewer inclusions the more value it would be. Colour plays an important role as well in the pricing because if the colour were rare then the diamond would be very valuable. As for the cut, different cuts have different values.

How Diamonds are Made

Diamonds are useful and beautiful stones that undergo a complicated process before being used in a variety of applications, most commonly known would that of the jewelry-making business.

While there are now laboratories that create synthetic diamonds in a span of a few days, it is the formation and production of natural diamonds that require very specific conditions.

Diamonds formed through natural circumstances are exposed to extremes in high pressure of about 45 to 60 kilobars and to comparatively low temperatures of about 900 to 1900 °C. These rough stones are mined or recovered through either pipe or alluvial mining.

Pipe mining refers to the extraction process found in volcanic pipes. In most locations, a pipe mine is composed of kimberlite, which is dug from the surface of pipes in rough opencast mining.

Once these are exhausted, the diamond miners start digging tunnels into the deeper parts of the pipes. The rocks recovered, which contain rough diamonds, are then moved to a screening plant where the rock bits are separated from the diamond bits.

It typically takes an average of 250 tons of pipes to produce a one-carat gem quality polished gem.

Allluvial mining, on the other hand, is located on riverbeds or ocean beaches. When diamonds were formed in pipes deep inside the earth millions of years ago, some of these separated and was carried out along the rivers and oceans.

In order to mine these diamonds, a wall is built to hold back the surf or water. Up to 25 meters of sand and rock can be bulldozed to reach the diamond-bearing level.

Once these are recovered or mined, the diamond-bearing earth is transported to the screening plants.

Of all the diamonds mined in the world each year, less than half are gem quality, which are used in jewelry making and display a high standard of excellence, usually with a clarity grading of flawless to near invisible inclusions.

The rest that are recovered are either near-gem quality or industrial quality diamonds. Near-gem quality diamonds can either be used to jewelry or industrial applications, depending on the actual stone.

As for industrial quality diamonds, these are usually of low quality or have a lot of blemishes and inclusions, and are usually used as drill bits and for cutting purposes.

All the diamonds recovered from mining will undergo a cutting and polishing process to obtain their final form, as we know it.

Although technology has played an important role in perfecting these techniques, cutting and polishing diamonds has its origins in India, where it was discovered by Indian lapidaries that a diamond can be made to sparkle and be smooth simply by grinding it against another diamond.

Nowadays, even with the use of machinery, diamond cutting and polishing can take anywhere from several hours to several months to complete. Some diamonds, especially gem-quality stones, are studied for months, even years, before the cutting and polishing process begins.

Each stone is different, and must be carefully studied and marked for cutting. That is why only experts commit to this process, as a diamond’s ultimate price and value may plummet due to a poor cut.

A diamond can usually stand to lose half of its original weight after this final process.

6 Handy Tips on Buying the Right Diamonds

Posted on by

Believe it a not; there are jewelers who are unable to differentiate a diamond cut from a diamond shape. Everyone is so hyped up about the carat weight and has totally forgotten about the other 3 characteristics of a diamond.
It won’t take you years or months to learn something about diamond. There are plenty of articles and information on the 4C of a diamond. Spend some useful time in the library or internet and learn about diamonds. Who knows, you may become an expert in diamonds.
1. Prioritize the 4 characteristics
There are much more about diamonds than just the 4Cs. But at the end of the day, the 4Cs are still the major factors influencing the quality and price of a diamond.
Before you start prioritizing the 4Cs, you got to know what your girl actually likes about a diamond. If she like big one, go for a diamond with big carat weight but with poorer quality in terms of color, cut or clarity. If she likes the brilliance of a diamond and doesn’t mind the size, choose one with excellent cut and clarity. Whichever the case is, prioritizing the 4Cs will give you a better idea of what diamonds will suit her taste as well as your budget.
2. Do a price research
Based on your list, you should have a rough estimate of the market price of the diamond you are looking for. If the price is out of your budget, try going for a grade lower than your expectation and you may eventually find one that suits you well.
3. Do some background research on the jewelry stores
If you have been doing researching, you would have come across information on cubic zirconium diamonds. These synthetic diamonds are D-color graded, flawless and cut to perfection. In short, a CZ diamond is a ‘perfect’ diamond. It is brilliant, flawless and yet cheap. Their prices do not increase exponentially with their quality unlike diamonds.
And there are also some natural diamonds which have undergone treatments to reduce its blemishes thus enhanced its appearance. It is still a low grade diamond and dishonest dealers may try to pass it off as a good graded diamond and sell you at a higher price.
So, before you start swiping your hard-earned money away, do some research about the jeweler as well. Ask your family, relatives or friend who have purchased from the dealer. Online forum is a good place to ask around and there are plenty of sites that provide reviews on jewelry store online.
Give the jewelry store a call, talk to their staffs and decide for yourself if you are comfortable with the store.
4. Always ask for a money back guarantee
There are risks in very form of transactions, so do buying diamonds. Protect yourself and minimize any risks by making sure that the store has the complete details about their return policy. It should include information about the validity period, what to do if you wish to return your purchase and their address.
As a rule of thumb, online stores should offer you no less than 21 days return policy. In fact, most of them have a return policy of 30 days.
5. Choose jewelers who provide grading reports
Certified diamonds will come along with a grading report by reputable gemology organizations such as GIA or AGS. Some online jewelry stores certified their diamond by in-house gemologists and they may be using different grading standards from GIA or AGS, while others may not provide the grading reports. Diamonds from top online jewelry stores generally comes accompanied with a grading report.
After you have purchased your diamond, you should get it appraised again with the grading report by a trained gemologist. The grading report will be very helpful in ascertaining whether the diamond you have bought is up to the specifications shown on the report.

Diamond Jewellery

Purchasing diamond jewellery is a very good investment option. Diamonds are precious stones and very rare and that is one reason why they are so expensive. Any diamond is primarily valued as per four basic criteria – cut, clarity, colour, and carat. The precious diamonds in the diamond jewellery that you buy are going to be the main highlight of your investment and hence it is important to know the basic information about diamonds as given below.

The cut of a diamond essentially means the manner in which naturally found crude diamond stones are polished and designed. A typical diamond has many facets or surfaces. Polishing a diamond in to a finished attractive dazzling stone requires very precision and skilled cutting.

Clarity of a diamond is the degree of transparency in a diamond. A diamond that is completely clear of any impurity is said to be flawless and is quite expensive. The clarity of naturally found diamonds is at times slightly obscured due to presence of other impurities like diffuse particles that are mostly minerals. Synthetic diamonds, being artificially created are completely flawless.

Colour of a diamond is anything between colourless to the yellow hazel extreme. The carat of your diamond jewellery is the mean weight of the stone. All these parameters are used while valuing a diamond and when you go out to purchase diamond jewellery you will find this basic information very resourceful while making a selection.

Your diamond jewellery has two main parts. The diamonds chosen by you that are set in some precious material. So when you are purchasing diamond jewellery you will have to consider two main issues; the diamonds to be selected and the medium or material in which they will be set. While you can purchase diamonds as per the design you like that is within your budget, the material used to set the stones has to be carefully selected.

You can choose from several alternatives like yellow gold, white gold, platinum, silver or even titanium. Although the diamonds will make your diamond jewelleryspecial and unique, the foundation material is also of paramount importance. There are many factors you have to consider to select the foundation material. For example, if the diamond jewellery involves pairs of diamond rings, then the foundation material should be of such a nature that it can hold the stones firmly over a long period of time. You don’t want your diamonds to slip off the rings. They are too valuable to lose, especially if it is your wedding ring. Thus, in this case, a material like platinum that is durable and quite pliable can prove to be a very good foundation.

For the above reasons, purchasing diamond jewellery from an online jewellery store is a very good idea. The reason is that you can view a great number of designs and materials before you make your choice. Also, the other benefits include ease of purchasing, safe and secure payment options that are instant, and the diamond jewellery will be conveniently shipped to the location of your choice within a few days to weeks.

Cultured Vs. Natural Diamonds

Posted on by
Reply

“Cultured” diamonds is one type of artificial diamond. They have been small and limited to industrial uses, while synthetic diamonds have been produced for decades. Cultured diamonds, then again, can be up to 2 carats and come in a selection of colors such as pink, orange, yellow, and the most common transparent diamonds, making them appropriate for jewelry accessories. Cultured diamonds are shaped using a recently invented production system that grows the crystals from a seed under high temperature and pressure.

Natural loose diamonds always have structural indiscretion or chemical impurities. Because of this, imperfections must be added to simulate the look of natural diamonds. While colored diamonds (for instance, Jennifer Lopez’s pink diamond engagement ring) are enormously uncommon in nature, they are cheaper to produce because they take only a few days to cultivate as compared to several weeks for transparent diamonds. The period for producing cultured diamonds may be shortened as the manufacturing methods are perfected.

Unlike cultured diamonds, cubic zirconia (shortened CZ) is made up of a different substance than natural diamonds. CZ consists mostly of zirconium dioxide. Consequently, its chemical properties are close to, but are unlike those of diamonds. While CZ is heavier, it does not have the ‘fire’ or light dispersion that diamonds have. In normal conditions, cultured diamonds and diamonds are considered 500 times harder than cubic zirconia.

There are a number of claims which states that cubic zirconia cannot be easily differentiated from a natural diamond when seen by the unaided eye. This may be true for people who are not in the jewelry business. However, simple lab tests can easily differentiate them because they are made of different materials. On the other hand, there is no way to differentiate between a cultured diamond and a natural diamond. This information causes huge dismay to the diamond commerce, which is racing to expand differentiating processes.

In order to prevent confusion, the companies that are manufacturing these cultured diamonds are taking procedures to mark their diamonds. For instance, they may laser engrave them or put in trace impurities. If this is not done, diamond buyers would not be able to know if the diamond they are buying came from a machine or from a natural mine. A natural diamond might command a high value due to the expense of mining and its apparent rarity. An unprincipled seller might pass off a far less luxurious cultured diamond as a real diamond.

Diamond Clarity by Gemisimo

What are the imperfections affecting diamond clarity?

A perfectly clear diamond (FL) is rare and expensive from a vast number of stones just a very small percentage are flawless, a great example can be seen in our diamond price comparison engine where you can easily notice that from our huge diamond database only a dozen are flawless (FL) diamonds and their prices are 20% higher from similar VVS loose diamonds. Most diamonds have imperfections; these flaws can be present externally as blemishes or internally as inclusions within the diamond.

 

Inclusions can be in the form of minute spots of black, white and other colors or as colored and uncolored crystals. These are usually caused due to trace minerals in the stone from which the diamond is extracted.

 

Blemishes include the presence of scratches, cracks or pits on the surface of the diamond. While minute cracks may not cause any major problems, some cracks may cause the diamond to split.

Depending upon the various imperfections diamonds have, the GIA has devised various grades for determining the degree of clarity. These grades are given to diamonds based on the number of inclusions, position on the stone, composition and size. Using a magnification of 10X, diamonds are ranked with the following grades. Here are some examples from our online loose diamonds search results:

•· Flawless (FL) Diamonds

•· Internally Flawless (IF) Diamonds

•· Very Very Slightly Included (VVS1) Diamonds

•· VVS2 Diamonds

•· Very Slightly Included (VS1) Diamonds

•· VS2 Diamonds

•· Slightly Included (SI1) Diamonds

•· SI2 Diamonds

•· SI3 Diamonds

•· Included (I1) Diamonds

•· I2 Diamonds

•· I3 Diamonds

 

As the abbreviations explain the grading, FL comprises of flawless diamonds while IF comprises of diamonds that are flawless inside but have slight blemishes outside. VVS1 and VVS2 diamonds have minute inclusions that are difficult to detect even by experienced graders. VS1 and VS2 diamonds have minute inclusions too while SI1 and SI2 have noticeable inclusions. Finally the I1, I2 and I3 diamonds are those which have imperfections that can affect the brilliance and transparency of diamonds.

Modes for enhancing a diamond’s clarity

Today various technologies have evolved for enhancing the clarity of diamonds. One example is laser drilling where lasers are used to drill out the internal spots and acid is used to wash them out. Cracks on diamonds can also be filled easily, but the treatments are considered temporary in nature. Ask for certification and if the details state that a diamond is ‘enhanced’ then be sure to compare the price. Enhanced diamonds are treated diamonds and as a customer you have the right to ask which treatments have gone into enhancing the stone, for further info refer to our Diamond Enhancements article.

 

What diamonds buyers must look for!

A perfectly clear loose diamond is not only beautiful but highly expensive when buying. Moreover, in an era where synthetic diamonds are in fashion, imperfections only go on to tell that the diamond is original. While perfect clarity is not the main criteria to look for while buying diamonds, buyers must keep the following issues about diamond clarity in mind while purchasing.

Type of flaw: A large visible crack may cause the diamond to break and must be avoided. Similarly a large blemish may also cause the stone to look dull and lifeless. Consider the kind of flaw your diamond has before purchasing one. Ask for certified diamonds such as GIA certified diamonds or EGL certified diamonds.

Location of flaw: Consider where the flaw is located and how it affects the appearance of a diamond. Flaws are visible only when diamonds are put in a particular position and one must avoid that while setting the diamond in jewelry.  
Size of the flaw: Look for a diamond that appears clean to normal viewing. If the flaw is of a bigger size, it would be visible to the naked eye. Trends indicate that most diamond buyers opt for stones with VS1 and VS2 grading over perfectly flawless stones.

Number of flaws: Finally if a stone has a large number of flaws, it would reduce the brilliance. Thus look for a diamond with fewer flaws so the brilliance of the diamond can be appreciated.

So before you buy a diamond go and take a look at the certificate, the drawing of the diamond will show you exactly how serious are the imperfections even if you are not a diamonds pro, you can also send us a copy of the certificate and we will do our best to explain to you about your chosen stone.

Diamonds dug out of mines surprisingly, only 20% have clarity suitable for usage in jewelry. The rest 80% diamonds are put to industrial usage. Among the 20%, many have visible inclusions and very few are flawless. How ever negative the term inclusions or flaws may sound, they do have benefits. The price difference between a flawless stone and a VS stone is enormous and thus by buying a beautiful diamond that has slight inclusions that the naked eye cannot notice you save big. If you are still unsure whether the diamond you plan to buy is a high quality one or not, experts at gemisimo are there just to guide you through a buying process.

Diamond Formation

Reply

The word “Diamond” comes from the greek word “Adamas”, which means indestructible. It is the only gem known to man that is made of a single element, Carbon, besides graphite. Diamond is completely made of Carbon atoms (Chemical Composition – ‘C’) crystallized in a cubic (isometric) arrangement. Diamond is the hardest substance on Earth. Diamond crystallizes in the isometric (cubic) system, and regularly forms cubes and octahedral.

 

Diamond form between 120-200 kms or 75-120 miles below the earth’s surface where we have extremely high temperature and pressures. According to geologists the first delivery of diamonds was somewhere around 2.5 billions years ago and most recent was 45 millions years ago. Large diamonds particularly large diamonds with flaws are extremely rare. The flawless diamonds are very valuable as gemstones.

 

Types of diamond deposits

 

Primary deposits
Diamondiferous pipes, which are ‘pipes’ of mineral-rich volcanic rock containing diamonds, are known as primary deposits.

Diamondiferous pipes are the solidified cores of kimberlite or lamproite volcanoes.

Secondary deposits
Deposits that contain diamonds which have traveled some distance from their original source are referred to as secondary deposits.

The diamonds that are now found in Namibia, for example, have traveled over 1,000 miles from their original source in southern Africa, transported by the Orange River.

Kimberlite, lamproite and komatiite are the only types of rock known to have transported diamonds from the Earth’s interior up to the surface in significant quantities.

 

According to science, the carbon that makes diamonds comes from the melting of pre-existing rocks in the Earth’s upper mantle. There is an abundance of carbon atoms in the mantle. Temperature changes in the upper mantle forces the carbon atoms to go deeper where it melts and finally becomes new rock, when the temperature reduces. If other conditions like pressure and chemistry is right then the carbon atoms in the melting crystal rock bond to build diamond crystals. There is no guarantee that these carbon atoms will turn into diamonds. If the temperature rises or the pressure drops then the diamond crystals may melt partially or totally dissolve. Even if they do form, it takes thousands of years for those diamonds to come anywhere near the surface.

 

It is interesting to note that “synthetic diamond” is the form of diamond predominantly used in industry. The process allows the removal of impurities and produces a product with consistent physical properties; most of the carbon comes from graphite. Synthetic diamond accounts for the majority of industrial diamond consumption.

 

Because it is the hardest substance known, diamond will cut through any material. Consequently, it is used as an abrasive and in cutting and grinding applications. Industrial diamonds are embedded in large steel drill bits to drill into rock for wells to find water, oil, and natural gas. It is also important in the manufacture of machinery for drilling and cutting metal machine parts.

 

The United States is by far the world’s largest consumer and market for industrial diamonds. It is predicted that the U.S. will lead the world in diamond consumption well into the 21st century.

Buying Diamonds Safely

Posted on by

In order to buy the best quality diamond there are things you must know and understand. Do not rush in and buy a diamond on an impulse because it is advertised as a ‘good deal’ or is ‘discounted’. There are no bargains in diamonds and diamonds that are of excellent quality, cut and colour are not sold off cheap! Always make sure you buy a loose diamond that has been independently certified and compare diamonds before making any decision.

Do not confuse a diamonds carat weight with the size of a diamond. Even though two diamonds may have the same carat weight their appearance in size and diameter measurements can very greatly. A poorly cut 1.00ct diamond may look like a 0.75ct diamond from the top because they have the same diameter measurements even though their carat weights are different.

Diamonds are sold by their carat weight. A diamond cutter always tries to retain as much carat weight and as few inclusions when cutting a diamond. Sometimes the cut of a diamond might be sacrificed in order to produce a diamond with a higher carat weight. Excellent, Ideal and Very Good cut diamonds will sparkle with more brilliance and fire than diamonds which are poorly cut with a lower cut grade.

Buying a loose diamond for an engagement ring is a daunting task with so many jewellers, diamond dealers and diamond internet websites these days. There is an abundance of information available to consumers, but not all of it is accurate. This is probably one of the most important considerations to make when buying a diamond. There is alot more to diamonds and their prices than just learning about the diamond’s cut, colour, clarity, and carat weight. All diamonds are unique, no two diamonds are exactly the same which is why it takes years of experience, training and learning to fully understand them.

Buy your diamond from a reputable diamond dealer. Most diamond buying guides advise you on the 4 C’s and suggest that you only shop at honest, reputable diamond dealers, but how does the average consumer determine this?

Our advice is to ask if the diamond is certified and to see which laboratory issued the certificate or grading report. The quality of the certificate, or lack thereof, goes a long way towards telling if you are dealing with someone reputable and professional.

A diamond certificate or grading report is only as good as the laboratory who issued it. A diamond certificate, is only useful if it is reliable and has been issued by a reputable independent laboratory which has no financial interest in the stone. If you’ve never heard of the institution that is offering a grading report, don’t hesitate to ask about its credentials and that of the people who graded the diamond.

a diamond certificate or grading report is a blueprint of a diamond which documents the details and statistics about a loose diamond such as the shape, colour, clarity, carat weight, proportions and finish of the diamond. A diamond certificate also confirms that the diamond is natural and is not synthetic or man-made.

There is also the undeniable fact that some diamonds are treated or enhanced in some way, and these diamonds are very difficult, and in some cases impossible to identify, without the correct laboratory equipment.

Synthetic diamonds are the latest threat to the uneducated consumer. If you are buying a diamond with out a recognized certificate (IE; a certificate recognized by either the WFDB, IDC, or CIBJO) it is possible that it may not be a Natural diamond at all.

Diamond certificates from respectable labs, meaning GIA, HRD, AGS or DCLA, are totally necessary if you want to compare diamonds intelligently. Laboratories such as GIA, HRD, AGS and DCLA issue grading reports of the highest international standards. All of these diamond grading laboratories utilize strict procedures, have the most advanced equipment, and affiliations which meet the strict requirements for recognition by international trade organizations.

It is up to you, the consumer, to verify the credentials of the diamond grading laboratory and the diamond merchant, wholesaler or jeweller you are dealing with when buying diamonds or engagement rings.

Be even more cautious of website dealers who issue their own ‘in house diamond certificates’ or ‘manufacturer’s grading reports’ as these simply are NOT independent certificates and they are NOT from a compliant laboratory.

Every diamond grading laboratory has a different set of parameters and specifications that they grade diamonds by and not all laboratories are as strict as each other.

In fact, some laboratories are popular with certain diamond dealers because they have a reputation for being generous with grades and are known not to be as strict as others. This is why at Diamond Imports we choose to only select and sell loose diamonds that have been independently certified by the following compliant and internationally recognized diamond grading laboratories – DCLA, GIA, HRD & AGS. This translates to Global Assurance.

Diamond grading laboratories which grade to IDC International Diamond Council rules, do not just use the opinion and expertise of one person. They must grade the diamond and have the opinion and consensus of three qualified diamond graders before the grade is applied to any diamond. In Australia, DCLA is the only IDC diamond grading laboratory.

Valuations or appraisals are NOT the same as a diamond certificate or grading report.

It is important to remember is that a grading report or diamond certificate does not include an appraisal, or any kind of statement about the monetary value of the diamond.

Diamond Imports is one of Australia’s largest importers of loose diamonds specialising in Excellent Cut and Ideal Cut diamonds, Certified diamonds and fancy shape diamonds. Diamond Imports will teach you everything you need to know about diamonds to make an informed decision when buying diamonds.
