The diamonds can actually do in a laboratory?

Diamonds have long been admired for their rarity, beauty and indestructible longevity for centuries. These features made which is very expensive. Add to this the fact that they are increasingly in demand for industrial sector and the use of Gems, and explains why scientists have wanted to grow diamonds in the laboratory for almost two years. However, this is only the latter part of the 20th century that the conditions required to replicate the formation of natural diamonds are eventually reproduce.

Natural diamonds are formed under conditions of chronic high temperatures and pressures over millions of years. However, synthetic diamonds can be made in the laboratory in a matter of days or weeks at most, depending on the production of diamonds.

So how they are made?

In fact, there are two methods used to create synthetic diamonds: the method of high temperature high pressure (HPHT) and chemical vapor method (CVM).

HPHT is the most widely used two methods. Actually, copies of the processes used to create natural diamonds. A small diamond seeds are exposed to high pressures, about 55,000 atmospheres and temperatures of 1400 degrees Celsius in the presence of graphite iron, which is the carbon source used to be diamond and iron or cobalt catalysts, which which act to expedite the process.

By way of chemical vapor high temperatures and pressures are again used to simulate the growth conditions of natural diamonds. However, the source of carbon used to be a half diamond from a gaseous compound of carbon which is then divided into their simple parts. The resulting carbon after diamond rains the seeds, growing is not.

CVM can be used for things diamond layer, such as cutting blades, but there are still many problems to succeed in front of a large gem-grade diamonds are grown using the CVM.

Both CVM and make synthetic HPHT diamonds to atomically identical and have the same physical characteristics as natural diamonds. However, a small diamond is always necessary to fuel the growth of diamonds. Without it, a diamond can not be made. So, in truth, diamonds can not do in a laboratory. They can only grow to a larger laboratory!

Synthetics have a unique growth characteristics associated with its rapid growth, allowing it is known from diamonds mined by testing equipment developed by laboratories to test large jewel. When identified as the work of man, which is carefully marked, recognized in every reputable jewelers like people. So when you come to buy diamond jewelry always make sure you know whether diamond is natural or synthetic, or be deceived!
