VS+ Purity HPHT Lab Created Dinmonds White Synthetic Rough Diamonds For Sale

Lab Created Diamonds Description

Cultivated diamond is synthesized by artificial simulation of natural diamond crystallization conditions and growth environment, and natural diamond has exactly the same physical, chemical and optical properties. Production time is perhaps the biggest difference between the two types of diamonds, with natural diamonds taking hundreds of millions of years to form and cultured diamonds taking just a few weeks to produce.
Scientists have mastered how to grow a diamond in a laboratory, which is much cheaper than mining natural diamonds.
1. High pressure high Temperature method (HPHT)
Growing diamonds requires an indispensable element: carbon (C). In the process of growing HPHT diamonds, pure carbon powder is compressed into a growth capsule and then placed in a incubation chamber at pressures of 5-6 gpa and extremely high temperatures (up to 1300-1600°C) day in and day out. Eventually the carbon atoms join together to form a diamond crystal. Many large diamonds over 10 carats can be produced in one go in less than two weeks.
2.Chemical vapor Deposition (CVD)
Breeding process of chemical vapor deposition method is as follows: first, place a piece of diamond chips in a vacuum box, the next in the chamber filled with a mixture of hydrogen and methane gas, the gas provides a carbon atom, under the pressure of certain heating, until the gasification of carbon atoms on the thin layers and layers of sedimentary, like rain, forming uniform diamond coating. It takes nearly a month to grow a one-carat CVD diamond crystal.
