A synthetic diamond is a diamond that was not produced in nature. Synthetic diamonds are produced through a physical or chemical process. Synthetic diamonds are produced in two main ways.
The first is referred to as High-Pressure High Temperature. This method uses very heavy presses to recreate the environment inside the Earth in which naturally produced diamonds are formed. Because of the low cost of this method, it is the most widely used today.
The second method for creating synthetic diamonds is a process called chemical vapor deposition. In this method, a base substrate has a carbon plasma placed on top of it. Carbon atoms deposit here and form a diamond. Synthetic diamonds are not just used in jewelry but have many other applications such as in tools and in electronics.
Synthetic diamonds are often used in the automobile industry in machining aluminum. Synthetic diamonds are often used in jewelry. The advantage of a synthetic diamond is that it often appears to the everyday consumer as just as brilliant and beautiful as a naturally created diamond but for a lot less money.
Synthetic diamonds are often created as colored diamonds. They are typically more profitable than non-colored diamonds because they are in demand from consumers, they are less expensive to make and they can be made rather quickly.
Colors range from the popular pink diamond to vivid blue, and even black diamonds are created. A recent increase in celebrities wearing colored diamonds has increased the popularity of synthetic colored diamonds as they are more affordable to the everyday consumer.
