Diamond is the hardest naturally formed mineral found on earth. It is used not only for making expensive and beautiful jewelry but also for making drilling equipments. Since diamonds are very hard, they are ideal for making cutting and grinding equipments. Diamonds can be used to cut, drill, grind and polish. Thus it is greatly used in various industrial applications. Some of the common equipments used are the diamond tipped drill bit and the saw blades. Diamond powder is used as an abrasive in industries. The diamonds used for these purposes are of lesser quality and are called ‘bort’. Thus, there are two grades of diamonds – the gem grade diamond and the industrial grade diamond. The industrial grade diamonds should be hard and have heat conductivity.

The demand for diamonds is greater than the supply, so the diamond drill is very expensive. Although, there are a number of types of drills, the diamond drill is a very essential piece of equipment in an industry that needs to do a lot of drilling. The diamond drill is actually a drill with the diamond drill bit attached to the end of hollow drill rods. The diamonds used are fine to micro fine diamonds. To keep the sharpness and hardness of the diamond drill, it is necessary to give it sufficient lubrication and cooling. The holes made are very clean and giving the best results. The drilling has to be done slowly so that the life of the drill bits can be extended for a longer period of time. Drilling is a laborious process. It is also a tiring and demanding task and uses up a lot of physical energy. But, it needs to be done.

The diamonds drills can make holes in any type of substance, right from a soft one to a hard one. It includes bricks, metals, concrete and any other material without giving out much noise. The holes can be made quickly without any vibrations and much effort, since the drill is made of hard diamond. The diamond drilling equipments are long lasting and penetrate fast to drill a hole.

The diamond drilling equipments are used in all kinds of industrial applications. We are generally not aware of it many uses. They are used by the construction industry for making holes in bricks, concrete and iron. It is used in the mining industry to drill holes at places where there are mines. Wherever holes have to be made for placing cables, where anchoring bolts have to be placed and also where load carrying machines have to be installed, the diamond drilling equipments are used.

There are two types of drilling techniques. The dry drilling technique is used when concrete, hard surfaces, pavements, bricks or any hard surface has to be drilled. The wet drilling technique is used when the place that has to be drilled is fully under water.

The diamond drilling equipments are of different types. Synthetic diamonds are used in the impregnated bit’s matrix series. The matrix layer has the diamonds in a powdered metal bond. They have a long life and also penetrate fast. They are used in many forms of drilling. Surface set diamond bits have a single natural diamond layer. They have a hard matrix compound on the face of the bit. They are used while drilling soft to medium hard surfaces.

Diamond reaming shell has natural or synthetic diamonds. It is used to attach the drill bit to the core barrel. The main work of the reaming shell to make a hole that is exact in diameter for the core barrel to go through, having enough space for a new drill bit, when the old one has to be changed. Long diamond reaming shells are also available for drilling purposes.

Diamond core bits are thing walled core bits that are used in a large number of applications. They are used to drill holes in are concrete, glass, ceramics and also in all kinds of pipes used in electricity, drainage etc. Wet cut drill core bits and dry cut drill core bits are available for various purposes.

Synthetic diamond polycrystalline is also used in making drilling equipments. They are used in making drill bits, reaming shells, saw blades etc. Polycrystalline diamond pads or cutters (PDC) are placed in rows of polycrystalline diamonds kept on tungsten carbide substrate on the bit face, to drill holes in areas that are too sticky or soft. You have PDC core bits and PDC drill bits which are cost effective and very useful in drilling and cutting activities.

The diamond drilling equipments are no doubt expensive, but they are very effective in making clean holes that are necessary for all construction, mining and power, drainage, gas lines purposes. We should check out the various companies that manufacture these equipments, obtain details about the equipments and the price and then order the equipment that we need. The internet would be the best place to gather all the information.

Man-made Diamonds

Renewed interest has spawned in the synthetic diamond debate, in part due to new color technology by the Gemesis Corporation. The company, located in Lakewood Ranch, Florida, has been creating cultured diamonds for over a decade.

Gemesis has always specialized in yellow diamonds simply because that is what the machines make, influenced somewhat by the nitrogen in the air. Recently though, the company has been experimenting with the creation of pink and blue diamonds—highly coveted and extremely rare, naturally occurring stones.

If this takes off, not only will Gemesis be able to provide an abundance of color, but it would also bring economy to the world of diamond buying, with greatly reduced prices.

It is no wonder De Beers is sweating bullets these days. They have a lot to lose if machine-grown gems become a standard in the industry. Typically these stones sell for about one-third of what their naturally produced counterparts would.

Though it hasn’t been the easiest ride for Gemesis and other synthetic diamond makers, there have been steady gains made. In January, the Gemological Institute of America (GIA) started accepting laboratory-grown diamonds for commercial grading.

Gemesis Chief Executive Steven Lux is hopeful. “By the end of next year, Gemesis expects to be making enough pinks to bring them out commercially. By 2009, Gemesis will have commercial quantities of blues,” Lux said. There are also plans to create different colors in the future, including the traditional “white” or “colorless” diamond.

De Beers, by far has been the biggest defender in this cultured vs. natural diamonds debate. De Beers spokeswoman Lynette Gould appeared confident when discussing the future of the diamond industry, though. “If synthetics do enter the jewelry market we believe that over time, production costs will fall, and synthetics will probably occupy a similar position in the marketplace to Cubic Zirconia, Moissanite, and other such materials,” wrote Gould.

To counter this notion that Gemesis’ real diamonds are even remotely similar to cubics, Gemesis recently hired Joan Parker, a former De Beers spokeswoman and marketing executive. Gemesis does not even approve of the term “synthetic” because of the fact that its stones are physically, optically, and chemically real diamonds.

The only difference is one is made by nature, and one is made by man. Pick your poison…or your treasure.

Should a Jewelry Designer Be Required to Reveal if Stones are Real or Synthetic?

The answer to this question has less to do with what the buyer is looking for than what the value of the stone is worth. A “real” stone has a higher value due to the rarity of the stone itself and what is involved in retrieving the stone. A “Synthetic” stone is man-made in a lab. Not only can they be made to demand, but they are also a lot easier to retrieve. Revealing from where the stone originate gives it a better since of how much it is worth.

A diamond from a mine is worth a lot more than a diamond created in a lab. Real diamonds had to be retrieved from the mine, which cost time and money as well as back-breaking sweat and tears from the miners. This causes an emotional price tag to be added to the diamonds. There are also a limited number of diamonds to mine, and it takes years upon years to make a new one. This also increases the value.

A synthetic diamond is made through a process called HPHT (High Pressure, High Temperature). According to wikipedia.org, “they are grown in split sphere high-pressure, high-temperature (HPHT) crystal growth chambers that resemble washing machines. The device bathes a tiny sliver of natural diamond in molten carbon at 1500 degrees Celcius and 58,000 atm (5.9 GPa)”. This produces a rough diamond which can be cut down to a polished size close to half its original carat weight. This process only costs the price of the machinery and workers. It is also a much quicker and a large number of diamonds can be made in a matter of days to weeks.

Once a jeweler knows that the stone that is being worked with is real or synthetic, then a realistic price tag can be assigned to the stone. When jewelers can purchase a dozen stones easily, the price that is paid for the stone is much less than if there were a limited number to purchase. This is supply and demand. For a real stone that causes the price tag to be much higher than a synthetic.

The price tag versus actual value of the stone is one of the foremost facts in the decision that should be considered. For the consumer to be able to make that decision, he or she must know if the stone is real or synthetic. It is essential that all stones be labeled correctly.

Demand for both gem and industrial diamonds is very strong. To fulfill this demand these days Synthetic diamonds are being produced in sufficient amount, this synthetically produced diamonds are being supplied for industrial uses, but these synthetic gems remain inferior and expensive, not suitable for the large jewellery market. The large gem market is still dependent on diamonds supplied by mining.

Demands for Diamond – A Simple Study

Demand for diamond is strong globally. The US$0.7 billion per year market for industrial diamond is now almost exclusively supplied by annual synthetic production of about 1000 million carats. Gem-quality synthetics remain inferior and expensive to produce, so the diamond jewellery trade is supplied by mining of natural diamond, derived from kimberlites, lamproites, and gravels.

Diamond Sales and Uses – A Global Scenario

Recently the world diamond selling market has achieved record sales, especially in the US where half of all gem diamonds are sold. Annual production of natural diamond, at a cost of about US$2 billion, has reached a total of over 110 million carats per year, and this production sells for about US$7 billion, resulting benefit of US$2 billion. Botswana, South Africa and Russia dominate the high quality production mostly handled in Antwerp and Tel Aviv, while Australia and Congo are leading suppliers of the low quality stones that are cut in India. The two-thirds or so of this annual supply of rough that is gem quality is reduced to between 20 and 30 million carats of polished goods and sold in jewellery for about US$55 billion. The one-third of all natural diamonds used for industrial purposes fetches only about 1% of mining revenue.

Diamond Needs in Future

The demand for diamonds is going to increase more in future. Both industrial uses as well as use of diamonds as gems in jewellery products will increase. So there is strong need of discovery of new sources of diamond along with new scientific approach of mining diamonds.

HPHT Treated Diamond

History of HPHT

The history of HPHT treatments dates back to 1955, when the General Electric Company first discovered the process for creating diamonds in the laboratory. This led to the creation of HPHT process, whereby GE first created a press where the required pressure and temperature could be maintained for the process. One thing led to another and HPHT treatment evolved through various presses like the tetrahedral, BARS and finally the cubic press. What began as an experiment for diamond color modification in synthetic diamonds has today evolved into usage for natural diamonds also.

Usage of HPHT Diamond Enhancements

HPHT treatments basically serve two purposes



Creation of synthetic diamonds
Color modification in natural diamonds

Creating synthetic diamonds: To obtain synthetic diamonds, carbon is put inside a grapite capsule. A seed is then inserted into this capsule and a catalyst is added. The diamond grows on the seed while the catalyst enables the crystallization to take place.

Color modification: Different type of diamonds react differently when exposed to HPHT treatments and a range of colors are obtained. For example, diamonds containing aggragated nitrogen, when exposed to HPHT can cause it to become single substitution nitrogen. In such cases, diamonds having green, orange and yellow hues can be created. In diamonds where nitrogen is negligible, the process is often used to produce colorless diamonds. Thus brownish diamonds when HPHT processed can obtain a colorless hue. A light pink color may also be obtained in some cases. In case of diamonds with negligible nitrogen and presence of boron, HPHT can alter the color. Thus brownish diamonds will lose the brown tone and boron will make the stone bluish in color.

 

Popular presses used for treatment

Belt presses: This was the initial form of press used for treatment. Here pressure is created by the usage of two high strength pistons that provide equal pressure in opposing directions on a sample. A series of rings surround the sample in order to contain the pressure.

Torid press: In this method, the two pistons apply pressure in a single vertical direction.

Cubic press: This uses many pistons that provide pressure from different directions. It is also known as a tetrahedral press.

Procedure of HPHT

If a customer intends to give diamonds for this treatment, the following procedure is used,



The stone is first inspected by diamond experts for cracks, fractures etc. Stones are also subject to chemical analysis using scientific equipment. Once it is confirmed that the treatment can be undertaken, the same is informed to the customer.

 



Depending upon the properties of the stone, the color that may be obtained after treatment is deciphered and the customer is informed about the same.

 



Pressure of over 1,000,000psi is applied by placing the stone in an internal pressure medium that distributes the pressure on the entire diamond equally.

 



The internal pressure medium is placed into a heat generating sleeve where temperatures start at 1800 degrees centigrade.

Pricing of treatments: Cost for these treatments varies with the size of the diamond. Also the total number of stones given and additional services like repolishing are charged extra. While these treatments are expensive,

 

Organizations and HPHT

Because HPHT is controversial, different bodies follow different guidelines for HPHT. As per the Federal Trade commission, HPHT treated diamonds must be disclosed to the user. General Electric follows this norm and all diamonds that are HPHT treated are laser inscribed with the terms ‘HPHT PROCESSED’, IRRADIATED. If GIA notes diamonds to be HPHT treated, it also specifies them as ‘HPHT ANNEALED’ or ‘Artificially Irradiated’. Such details are displayed prominently on the grading report under ‘origin’ in the ‘color’ section of the report.

 

Pros and cons

The HPHT treatment of diamonds is a controversial issue because it has both advantages and disadvantages. These are further discussed as under.

Advantages



The treatment is permanent and diamonds are stable in the normal conditions of wear and care.

 



It can dramatically alter the color of brownish diamonds to make it more appealing. Light brown color diamonds can be rendered almost colorless using this process.

Disadvantages



The process causes surface graphitization and the diamond needs to be polished to remove it.

It is difficult to differentiate between regular natural diamonds and HPHT treated diamonds.

 



It can cause marginal weight loss in a diamond.

It can reduce the clarity of the stone.

Disclosure

As HPHT has become more commercially available, today there are various methods available to detect if your stone has been HPHT processed or not. At the basic level diamonds over 0.5 carat can only be HPHT treated. A trained gemologist may use equipment like the SSEF spotter and crossed polarization filter to detect the same. DiamondSure is also used to separate cape diamonds from the rest. At the next level FTIR and UVVIS spectroscopes are used and synthetic and PT treated diamonds can easily be identified ere. Besides this, renowned laboratories have many other proprietary procedures that they use to identify such diamonds.

With all sophisticated equipment it continues to be difficult to detect HPHT processed diamonds at many instances. It is thus important that you purchase diamonds from a trusted vendor online or offline. Diamonds accompanied with a certificate from a reputed laboratory like GIA also ensure that diamonds are completely natural. You could also choose signature or top of the line branded diamonds to protect yourself. Finally, if you cannot afford GIA stones, make sure to opt for a diamond that is accompanied by a certificate from a renowned laboratory.

Look Elegant With Diamonds

Do you know that diamonds are billions of years old already? Yes, it does not look like it, right? That is the most precious attribute of the diamond – the ability to withstand the tides of time. Its beauty never fades though it is very old already. It has an eternal glow that not all gemstones of the world possess. It also has served as the symbol of wealth or royalty for decades because of its value and the eternal allure of this gem.

A diamond is very strong. In fact, it is regarded as the hardest natural mineral on earth to date. It has a score of 10 in Mohs scale of mineral hardness. A diamond can only be scratched by another diamond; however, if two diamonds are scratched together, both gems will be damaged. A diamond can also cut through glass! A diamond’s rarity is measured through its color. It is regarded that a crystal clear diamond is the most common diamond while the shades of violet and pink are the rarest.

Where do diamonds come from? Like all gemstones, it is taken from the fathoms of earth. This is also mined. Diamonds are formed at a high-pressure area of carbon but at a lower temperature compared to other gems. However, the ground is no longer the only source of diamonds. Today, even laboratories can actually serve as a diamond mine. Yes, there are now man made diamonds that are less pricey compared to the natural diamonds. How is this possible? There are materials called diamond simulants. They look like diamonds, but not really diamonds. They are usually other gems that can be a replica of a diamond.

A diamond simulant can be either natural or artificial. The natural simulants are usually gems by itself such as topaz, beryl, and quartz which are then processed to look like diamonds. These gems have above average hardness and low refraction indexes. Artificial simulants, on the other hand, are those which are made in the laboratories, silicon carbide (moissanite), and cubic zirconia. With the progress of diamond trade increasing demand for materials required to process diamonds are also increasing.

Please bear in mind that laboratory processed diamonds or the artificial ones are not fake diamonds. They are actually considered as authentic and genuine diamonds; only unnatural. A good example for this is the new Star Hybrid simulated diamond, which has the same clarity, quality and beauty as the naturals have.

It is common for a synthetic diamond to be made of cubic zirconia, or moissanite. There are companies who have researched thoroughly and have gone into the next level of diamond processing detail. They can actually process diamonds that are of better quality and appearance than of those that use the classic silicon carbide.

Truly the diamond has beauty that no other gem has. Its natural form may be costly, but now, there are cheaper diamonds which are man made but have the same allure as the naturals have and still possess the symbol of splendor in it.

Amazing Milestones in the Artificial Diamond Technology

From the beginning of  history, the subject of precious stones have been surrounded by art, fascination, religion, mystery, and the timeless appreciation for beauty. Among all the precious gems, the diamond has by far exceeded even ruby in elegance, grace, and hardness. Scientists believe that the natural creation of diamonds took billions of years where carbon dioxide were  subjected to intense heat and geological pressure until it comes out from the bowels of the earth truly transformed. This amazing metamorphosis of the black-coloured carbon dioxide to the sparkling beauty that is the diamond took billions of years in the making. As such, the diamond is truly a great creation. That is why the diamond has become a symbol of perfection, timeless love, and pure emotion.

Yet the human being, in an equally amazing feat, was able to discover the secrets of diamond making, circumventing billions of years in able to create the first man-made diamonds in just a few days! The time has arrived for the new era of man-made diamonds. Yet from the time when the first artificial diamond was created, new unbelievable breakthroughs have been made.

Below is the process of the development and progress in the creation of man-made diamonds:

The first synthetic diamonds simulated is the natural process by which carbon dioxide was subjected to intense pressure and heat. This is what we call high pressure, high temperature (HPHT) technology wherein a machine squeezes on carbon dioxide while intense electricity was applied. After only a few days of this process, the first gem-like quality man-made diamond was created. This invention literally kicked off a new era of commercially produced diamonds. These diamonds are a lot cheaper and can actually imitate the beauty and elegance of natural diamonds. On closer inspection however, these diamonds are not as clear and pure as the real ones.

A breakthrough in diamond making that has created an almost perfect replica of real diamonds was done with the method called chemical vapour deposition. This process begins with a real diamond. A tiny diamond is bombarded with carbons under specialized conditions of heat, pressure and microwave beams so that this real diamond begins to grow in perfect sheets and angles almost overnight.

New milestones have now been reached with gemstone composite technology, wherein there is an actual molecular bonding of the diamond and the sapphire crystals.  This created a hybrid gemstone called the New Star Hybrid diamond simulant. This new hybrid gemstone is harder than moissante created by Israeli High-Temperature High Pressure fusion technology in a process called “FCVA-Ion Jet Beam- Diamond Seeding”. The New Star Hybrid diamonds demonstrates the substantial, elemental and visual characteristics nearest to the 1-3 billion years old natural diamond. Among all the man-made diamonds to date, the New Star Hybrid diamond alone displays the clarity, brilliance and unparalleled elegance of real diamonds.

Coloured Diamonds.  Yet technology never stops. Now, artificial diamonds can come in different colours. Groundbreaking research has now made possible to put colour into diamonds so that they come in pleasing shades and hues.

Another mindboggling breakthrough in this field is the coming up of coloured diamonds. Now you can choose different hues and shades of diamonds that even Mother Nature was not able to accomplish in billions of years.

Lab created diamonds is also known as man made diamonds. These diamonds are gaining much popularity in the modern world because of their affordable price and diamond-like characteristics. According to some analysts, real diamonds are priced 40% higher due to the control of some big companies in the diamond mining industry. Because of this fact, more and more manufacturers are looking into the profitability of lab created diamonds. With the aid of modern technology and science, man made diamonds have the same luster and brilliance like that of real diamonds and you can get them at a reasonable price.

The man made or created diamonds are divided into different categories and types depending on their structure and methods of growth. The 4 categories for created diamonds are the HPHT large single crystal diamond, HPHT grit, CVD single crystal diamond, and CVD polycrystalline diamond. The types of simulated diamonds include the hybrid diamonds, white sapphire, cultured diamond, Russian diamonds, white topaz, YAG, and the diamond nexus.

Just recently, hybrid diamonds were launched by major jewelry stores. Hybrid diamonds were created with the use of FCVA-Ion Jet Beam Diamond Seeding. This diamond alternative is more affordable than cultured and synthetic diamonds. You can get the hybrid diamonds in different jewelry offerings like diamond rings, designer rings, engagement/wedding rings, 3-stone rings, solitaire rings, bracelets, and pendants. All these jewelries boast of artisan designs and unmatched brilliance. The hybrid diamond was hand cut by the diamond cutters from Israel. Such diamonds possess the same clarity, brilliance, and hardness of real diamonds. It is sold at $800/carat. In just a matter of months, it is expected that hybrid diamonds can achieve higher sales than other diamond alternatives.

The lab created diamonds are structurally and chemically identical to mined diamonds. Most of today’s man made diamonds are off white colored and very few ones are created colorless possessing the same brilliance of real diamonds. A real diamond seed is used to grow the synthetic, cultured, man made, or created diamonds. It will only take about 3 months to generate a created diamond. White diamonds are hard to produce because they need a nitrogen-free environment. Such set up is difficult to achieve and the growing process tends to be longer. Because of these factors, good quality lab created diamonds are a bit pricey.

If you can’t afford the high quality diamond alternatives, you can still opt for low cost jewelry like common diamond simulants. Shop around and find simulants that cost lower than $50 but don’t expect it to last for a long time. For special occasions like weddings and engagements, you can go for Russian brilliants and stars, white sapphire, and the hybrid diamonds. The Russian diamonds are sold at $280/carat, and white sapphire at $220/carat. You’re sure to get a good deal for your money because the diamond jewelries look like real diamonds. The choice is up to you so try to shop wisely.

You have a wide range of choices when it comes to man made diamonds. Pick the right one now for your loved one.

The diamond is often associated with grandeur and beauty. True enough; the diamond possesses unmatchable beauty that never fades away even through years. Because of its brilliance and clarity like no other stone, it leaves everyone dazzled and amazed by its allure. Due to its unfading charm, the diamonds are very expensive. Also, it takes millions of years for diamonds to be formed in the depths of the earth. Nowadays, the high socialites of the society are often the ones who purchase designer diamond rings which symbolizes their social status.

Nevertheless, present life technology is far more advanced than past life technology. Ever since, technology has rapid growth that almost every week there are new inventions and innovations. With the vast advancement, even the precious diamonds can now be man made diamonds! These gems are exact copies of natural diamonds but have the same beauty and charm as the natural diamonds.

Now, you might agree to the statement that lab-created diamonds are fakes. Well then, it is not true. It has been just a bad connotation as these diamonds are unnatural. In fact, they are even considered as real diamonds in the market!

How are synthetic diamonds formed? These diamonds are actually made from diamond material. These synthetic diamonds can act and be seen like a natural diamond. The new synthetic diamonds are cut and processed to look like diamonds and then put up into a series of processes to produce a simulated diamond. These are then cut into the desired shapes in order to fit in the accessory or adornment wherein it would be put.

A new generation of hybrid diamond is the New Star Hybrid simulated diamond. This man made diamond possesses the same clarity and brilliance a natural diamond, and cost 1/10 the price of synthetic diamonds. This diamond is a newly created one and is very fashionable. Apart from that, its materials are of real diamond, way beyond the regular cubic zirconia.

If the price is the topic, it is guaranteed that created diamonds are way cheaper than the natural ones. Why? This is because man made diamonds undergo through a shorter process of production and its materials are not that extravagant. With this, diamonds have become more affordable to the public.

If there is a suitable motto for man made diamonds, the statement “elegance without extravagance” would suit best. Having your wallets empty for diamonds is no longer necessary with this good alternative. The successful rise of created diamonds has pumped up the diamond trade worldwide because diamonds have become more affordable. Maybe you are thinking that the classic moissanite and cubic zirconia are the main materials, but no, there are few companies that have gone deeper into researches with regards to diamond production and have produced a better substance for better diamonds.

The technology of modern life has further advanced into the next level. As the world’s progress becomes faster everyday, almost everything is now possible with technology. Now, even the grandest gem known as the diamond can now be made by human hands.

Sona Diamond custom jewelry is the world?s highest-quality, man-made diamonds and they have a real diamond layer and the same brilliance, clarity and created diamond hardness, to a natural diamond on the market today.

Diamond the Multifaceted Gem

Everyone knows that diamonds is the hardest gemstone and women all over the world go crazy to own a diamond jewelry. This beautiful gemstone is renowned for its lustrous beauty, but very few people know of its ability to be used in other fields like electronics, machinery etc.The two aspects of this gem stone are so diverse in association and nature that one does not really connect the two uses with each other.

The diamond has certain very unique properties that enable it to be used in these various applications. It is the hardest substance on earth, has an extremely high thermal conductivity, is optically transparent and has high electrical resistance.

The hardness property of the diamond makes it amenable to be used as a cutting tool, especially for hard substances like marble, granite and hard wood. It is embedded in mechanical tools to enable the shaping of engine blocks and automotive components.

Once the process of developing synthetic diamonds was discovered, these synthetic diamonds were obviously the most preferred option for use in machinery. Apart from the cost, there are many other benefits of using synthetic diamond in tools. synthetic diamond growth can be controlled and monitored to produce desired shape and consistency. This is not the case with respect to natural diamonds where nature determines the shape, size and contours of the diamond based on various random natural events. Since the development of the synthetic diamond takes place in a laboratory, the level of impurities and mineral inclusions can be controlled. Due to these reasons and more the synthetic diamond today is sturdier as compared to the natural ones.

Another property that lends itself to use in mechanical work is that of thermal conductivity. The type IIa diamond can conduct up to 5 times more heat than the metal copper. The fact that it can absorb high levels of heat means that it can be used to reduce the friction in many engineering parts. Including the diamond as a ‘heat sink’ helps in extending the life of the machinery since it avoids wear and tear due to friction and heat. ‘Slices’ of synthetic diamonds are also be used for other industrial and surgical tools.

Much research is being done to use diamond chips instead of silicon chips in computers and it is being said that such computers would be 1000 times faster than the existing ones.

Even though the diamonds were being produced synthetically in the early 1990′s, they had not made their appearance in the jewelry industry. Large synthetic diamonds could be used only by using a lot of energy and ultra-modern technology. Since the engineering and mechanical market needs were yet not being met completely by the synthetic diamond supply, the proliferation of the synthetic diamond in the jewelry industry was abated. Another reason why the synthetic diamonds did not make their way into the studded necklaces was the fact that most of the synthetic diamonds being produced were still yellow or brownish in color.

The development and growth process of large diamonds required for the tools industry itself took too long. In 1990, De Beers claimed to have produced the largest synthetic diamond; a yellowish brown piece that was about 14.20 carats. This diamond alone took 500 hours to grow. Three years later they reported having produced a 34.80 carat crystal that took 600 hours to grow. Another few years and De Beers claimed that it was possible to produce 30 carat crystals in lesser time. But now one can find synthetic diamonds in many fancy colours and in white colorless shades too.

Even though there were great obstacles in perfecting the art of making gem quality synthetic diamonds, some companies forged ahead and continued to research the process. The challenge that they faced was that they could not avoid the nitrogen from entering the diamond while during the process of production, the gas that gives the diamonds the yellow color. GE was the first company to produce an almost colorless synthetic diamond by eliminating nitrogen from the process. This was done by using a metal flux, a substance that melts and dissolves other material in it. Special compounds were added to the metal flux to keep the nitrogen from entering the process chambers. Even though De Beers had also discovered the art of making synthetic colorless diamonds, neither company released their experiments and the colorless gems that came from them into the market. However, a Thai-Russian joint venture in Thailand distributed lab made colorless diamonds in the market.

Since the jewelry market does not require large pieces, these colorless synthetics are faster to grow, produce and sell in the market. Though the synthetic diamonds caters to a larger audience of the gem industry, they increase the possibility of being swindled, fraud and non-disclosure in the trade. As the production process is perfected and better quality colorless synthetics are produced and marketed each year, the challenge for the professionals in the jewelry industry becomes harder.
