Synthesis (Details on gem synthesis)

Synthetic diamonds are often yellowish in color (rarely used for gem purposes, more commonly used as diamond grit for industrial purposes. Modern synthesis of thin film diamond has other industrial applications).

A 5 mm diamond (0.5 carat) takes over a week to grow. Synthesis requires:

• high pressure
• high temperature
• a special apparatus

Synthetic diamonds can sometimes be distinguished from natural diamonds by the presence of flux inclusions (Ni, Al or Fe).

The first synthetic diamonds were produced by General Electric in 1954. A synthetic diamond is basically a rock that has the durability, refractive index and hardness of a natural diamond – but it is made by man. A synthetic diamond should not be confused with stimulant diamonds, such as glass, cubic zirconia, or moissanite.

Although the technology for synthetic diamonds came into play in 1954, no synthetic diamonds were ever seen on the market until the 1990’s. This was due to the fact that it took many years for General Electric to produce a synthetic diamond that could compare with the quality of a natural diamond – and when they figured out how to do it, they found that it cost more to produce a synthetic diamond than it did to mine and cut natural diamonds.

Finally, a small company by the name of Gemesis Corporation figured out a way to produce synthetic diamonds that were of the same quality as natural diamonds, at a cheaper price. Today, Gemesis produces synthetic white diamonds, and colored diamonds as well. These diamonds sell for about 1⁄3 of the cost of a natural diamond, but there is a shortage of them, and they are hard to find. In fact, it seems that synthetic diamonds are rarer than natural diamonds!

The Qualities of Synthetic Stones versus Natural - synthetic diamond jewelry

(synthetic diamond jewelry)

Physically, there are several differences between a synthetic stone and a natural one. (synthetic diamond jewelry) Again, the most ironic difference is that synthetic stones are TOO perfect. (synthetic diamond jewelry) Created expressly for jewelry purposes, their basic shapes are made to fit the type of jewelry they are meant to be set in. (synthetic diamond jewelry) Even their crystal structure is mathematically precise with no deviations whereas a natural gemstone will often have a flaw or two in it's matrice (and if it does not, a perfectly unflawed natural gem's price will be HUGE). (synthetic diamond jewelry) The chemical composition of the gem is likewise pure for synthetic gemstones, whereas natural gemstones may often have trace elements mixed into it. (synthetic diamond jewelry) These small imperfections are how most jewelers tell the difference between a natural and synthetic stone. (synthetic diamond jewelry) Price wise, synthetic gems can offer a person much more beauty and value for their money; natural gemstones of high quality are very rare and thus expensive, whereas the mass produced synthetics are physically the same but cheaper by anything from half to a quarter of the price. (synthetic diamond jewelry)

For long term investment, however, natural gemstones of high quality are a better deal because of their rarity; their value appreciates over time, whereas the price for a synthetic remains constant. (synthetic diamond jewelry) The price may even drop over time, especially for factory-made synthetic gemstones; natural stones and lab grown stones have no physical degradation over time, but factory-made stones, being made in a hurry, are not quite as durable as the real thing. (synthetic diamond jewelry) For this reason, lab-grown synthetic gemstones are becoming more and more popular over quick factory machine-made synthetics. (synthetic diamond jewelry)
