A national standard for synthetic diamonds led by NGTC is being developed.

An equiaxed crystal body consisting of carbon atoms formed wholly or partly by the growth of an iOL.

The physical properties, chemical composition and crystal structure are basically the same as those of natural diamond, mossberg hardness 10, density 3.52 (±0.01) g/cm³, refractive index 2.417, dispersion value 0.044.
In July 2018, the FEDERAL Trade Commission (FTC) changed the 62-year-old definition of a diamond to recognize a lab-grown diamond as a diamond.

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.
