The truth of Synthetic Diamonds


Synthetic Diamonds

Synthetic diamonds are diamond crystals produced in laboratories across the technological process, as compared to natural diamonds, which are produced deep within the earth through geological processes. Synthetic diamonds are not to be confused with fake diamonds, as it is known as diamond-like carbon, which is amorphous hard carbon or diamond stimulants, which are made of other materials such as cubic zirconia or silicon carbide.

Synthetic diamonds are actually real diamonds, but they are produced in laboratories or man-made, and depending on the procedure may be even better than natural diamonds. How to create a synthetic diamond is relatively easier than mining and processing of natural diamonds, which is why these stones are usually used in many industrial applications such as drilling and cutting tools, as well as in electronics.

The production process of cultured diamonds discovered a French chemist Henri Moissan in 1892. This process created a small diamond fragments of coal heating, which is carbon, the extremely high temperatures in the crucible of cast iron.

It is then rapidly cooled by immersing the crucible in cold water, causing it to shrink, which then creates enough pressure to the molten gel into small diamond carbon fragments. After the process Moissan was the first commercial application of synthetic diamond production developed by Tracy Hall for the General Electric Company in 1954.

This manufacturing process is known as HTHP or high-temperature high-pressure management, which was improved and was used to make industrial-diamond to this day. Another major process that is used to create synthetic diamonds is a chemical vapor deposition, or CVD method, which was developed during the first 1980.

HTHP technique applies a combination of heat and pressure on diamond seeds using either four-tetrahedral anvil press or six-anvil cubic press. This is a process that seeks to imitate the natural conditions for diamond formation inside the country. CVD method on the other hand, delivers vaporized carbon-plasma mixture of hydrogen, which is activated on the diamond seed using microwave energy, which then allows the gas to the substrate.

This is a diamond seeds grow in successive layers.

Both processes can produce cultured diamonds in the range of just a few days. These stones may have the same hardness, cleavage, dispersion of light, refractive properties, specific gravity and surface gloss natural diamond, and may even contain small inclusion. Some cultural diamonds are even better than their natural counterparts.

These are just some of the known synthetic diamond producers Apollo Diamonds, Chatham gemstones, Gemesis Cultured Diamonds and Created Gems Taurus.

These companies produce a number of laboratory diamonds, because they are also called, from D colorless diamond luxury diamonds. Most synthetic diamonds will have a slightly yellowish tint because of nitrogen impurities that are present in its manufacture.

These cultural diamonds can be distinguished from natural diamonds by using one of the following: infrared, ultraviolet, or X-ray spectroscopy. UV its heyday can also be measured with the tester Diamond View.
