Cut Diamonds

Diamonds that have not been placed in a setting are referred to as loose diamonds, and are generally sought after by investors and professional retail jewelers. Any purchase of loose diamonds should be accompanied by a certificate of appraisal and value.

The certification, which should always be based on an appraisal and analysis done by an outside, independent third-party agency, is more properly known as a diamond grading report. This report describes your loose diamonds in terms of weight in carats, clarity of the gems, color and cut. The individuals who perform this service are known as gemologists, and have received specialized training in this particular sub-field of geology. Gemology focuses on the study and analysis of precious stones and gems.

When loose diamonds are accompanied by such a report, they are known as certified. Anyone considering an investment in such diamonds, whether they are for use in diamond jewelry or as a hedge against inflation should make sure that their purchase consists of certified loose diamonds.

The job of a gemologist’s certification is not to assign a monetary value on loose diamonds; that happens in the marketplace. However, such a report is used to determine such a value. The weight in carats (a carat is roughly equivalent to .015 of an ounce, or two-tenths of a gram) is the most obvious basis of valuation; however, if the gem has a “cottony” appearance inside, this can affect the value negatively.

Certified diamonds are evaluated on what are known as the SI3 Clarity Scale and the Color Scale. The Clarity Scale was developed by the Gemological Institute of America (GIA); it ranges from “FL” for “flawless” to I3 for “Imperfect,” i.e., cracks and occlusions easily seen by the unaided eye.

Colored diamonds are rated on a scale that describes the gems in terms of hue and saturation. They are labeled with a letter of the alphabet from D to Z, ranging from virtually colorless to gems with a deep hue. Diamonds can be almost any color; the color variations include pink, green, blue, purple and amber, and are caused by chemical reactions during the diamonds’ formation. Such gems can be worth substantially more than “white,” or clear diamonds.

Control of the diamond market is concentrated in relatively few hands, centered around Antwerp, Belgium, where the diamond cutting industry was born over 500 years ago. These wholesalers recommend that diamonds be certified either by the GIA or the American Gem Society Laboratories.

Because of the way the analysis is done, it is impossible to perform a certification on mounted stones; loose diamonds should be certified prior to placement in a setting, ring, or watch, and the seller should provide documentation that such services have been performed.

However, this all-time-hit fashion jewelry can be found with some innovations too in its design. Unlike the most popular versions of solitaire rings in which the diamonds are given an ‘elevated position,’ the modern solitaire rings are coming with diamonds with a ‘lowered placement’ too.

Pave Diamond Engagement Rings : This is another classic version which prove to be the first choice of many wives-to-be. This is more popular for the way the tiny diamonds are patterned in an artistic and decorative way on its surface.

Looking at the rows of closely-fixed’ diamonds, with their bases wrapped with costly metals such as gold, placed within the holes made on the surface of the ring is a treat to watch. Most importantly, these diamond jewelry can be found at cheaper rates despite being made of using a cluster of diamonds.

Colored Diamond Engagement Rings : This ‘colorful’ jewelry trend is here to last for long. Such rings look bold and are being considered as the next big thing in the market of summer marriage. Such rings are being bought by those who want to give their girls a hint of their bold and colorful nature.

So if you are planning to buy a ring this summer, look out for something made of diamonds in pink, yellow, purple etc and the make the engagement ceremony as colorful as possible. Definitely, the color of this diamond jewelry trend is not going to fade way easily, literally. Be sure.

All-diamond Engagement Rings : Probably, this is the only stuff in the market which you can call a pure ‘diamond’ ring in its most literal sense. You will find diamonds placed not only in the center, but this is a special ring stuff which has tiny diamonds placed all around the ring. Thus you will not able to see even a fraction of the metal which the ring is made of.

However, this can be costly at some extent. But the gentle smile on the face of your girl, which this sparkling stuff is capable of bringing will patch up the holes in your wallet too easily.

Triple-diamond Engagement Rings : This is the most unique and the latest one. The three diamonds placed on the ring have got a philosophic connotation as each of them manifests your days before engagement, your day of engagement and your day after engagement, respectively.

So if you want to tell her how committed you are to her, don’t wait to buy her this beautiful stuff made of three glittering diamonds. These diamonds can be placed on this diamond jewelry in various patterns. They can be slightly raised or placed on a ‘twisted top’ or placed evenly on the surface. Also the diamonds can come in various colors and shapes too such as oval or square etc.

Contrary to what we commonly know, diamond jewelries are not always clear.  Colored diamonds are becoming more popular compared with the usual white and transparent diamonds even though naturally colored diamonds are more expensive.  Some companies are giving some of their diamonds color treatment to make it more suitable for some customers, budget-wise.

Treating diamonds with color would be by inducing the stones into extremely high heat to change the color.  It could also be painted.  When appraising color-treated diamonds, they tend to be more affordable since the color are less intense compared with the natural ones.  

There are different shades and colors for naturally colored diamonds.  But there are popular color shades and combinations, they are the pink, blue, brown, yellow, orange, green and red.  Interestingly, there are also black diamonds.  Yellow colored diamonds are the most common, while those in red, blue and green are the rarest.

When buying naturally colored diamonds, they are evaluated and checked just like the white and transparent ones.  The 4 Cs are still used in grading colored diamonds:  cut, clarity, color and carat.  However, the way or the factors how colored diamond are inspected are different.

• Color.   Naturally colored diamonds’ value would depend on the intensity of its color and its hue.  The more intense and vivid the color is, the value of the diamond also increases.  There would be times when there are traces of other color.  If the traces of the secondary color magnifies the beauty of the stone, then that would be great for the value of the stone. But if the underlying color is not complementing the main color, then it lowers down the diamond’s value.

• Cut.  A diamond’s cut gives the brilliance to the diamond.  The cut would enhance the intensity and the shade of the diamond’s color.  Most colored diamonds are in round, oval, and princess cuts.  There are also some that would be heart shaped and other unique shapes.

• Clarity.  Clarity is important for white and transparent diamonds, but for naturally-colored diamonds they may not be as important.  

• Carat.  Carat is all about the weight of the diamond and not about the size.  Of course, the bigger it is the heavier it will be.  The heavier the colored diamond, the higher its value.  

Just like when purchasing white diamonds, obtain a grading certificate from the retailer.  Make sure that the certificate is issued by international laboratories like the IGI, GIA or EGL.  This certification would be your assurance that what you have bought is indeed a natural colored diamond and not a stone that was tampered with.

The most popular colors would be in yellow and pink.  There are celebrities who fancy wearing colored diamonds.  Over the years, the demand for other colors is also increasing.  Another subject of curiosity would be the black diamond which is sometimes associated with both luck and being unlucky.  Most legends would say that black diamond jewelries are cursed and would bring bad fortune to those who own it. But different from other colored diamond jewelries, black diamonds are mainly used for industrial purposes.
