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!

In their most natural form, diamonds are – well – quite ugly. They have no luster or shine, and in fact, look like nothing more than broken glass. A diamond must be cut, and then polished before it actually becomes a thing of beauty.

Diamonds are cut with saws, into round shapes. From the rounded shape, other shapes may be cut, such as heart shapes – but the shape is less important than the quality of the cutting that is being done. If the diamond is poorly cut, it will lose light, and it will not sparkle and shine very well. Each facet of the diamond must be carefully cut into the geometrical shapes that allow the diamond to sparkle and shine, then the entire diamond is cut into a specific shape, such as an emerald cut or a princess cut diamond. Once the cut is done, the diamond is put into a dop, which resembles a cup with another diamond – only a diamond is strong enough to smooth the edges of another diamond.

Once the diamond has been cut and shaped, and had the edges smoothed in the dop, it is polished on a scaif or a diamond polishing wheel.
