5 Carat To 8 Carat Greenish HPHT Rough Lab Made Fancy Colored Diamonds For Making Fancy Color Stones

Lab Made Fancy Colored Diamonds Description

There are two main methods to make Rough Lab Grown HPHT Synthetic Diamond: one is high pressure and high temperature method (HPHT), the other is chemical vapor deposition method (CVD).

HPHT is the primary method used to grow rough diamonds in a laboratory. At present, the world's popular high-temperature and high-pressure synthetic diamond equipment mainly includes two side top, six side top and bar split sphere or improved split sphere.


Will Rough Lab Grown HPHT Synthetic diamonds be conflict with mined diamonds?


Many people have similar worries: since diamonds can be created in lab, can they be mixed with natural diamonds? If I want to buy natural diamonds, will I be cheated by using the price of natural diamonds to buy lab diamonds?

With professional equipment, the comparison of the color, crystal shape and crystal surface characteristics, internal inclusion characteristics, absorption spectrum and ultraviolet fluorescence characteristics of the tested diamonds can "completely distinguish the artificially cultivated diamonds from the natural diamonds". After all, natural diamond crystals were formed billions of years ago, while artificially cultivated diamonds can only be formed in a few days. There is no difference between the two, and it can be completely distinguished by professional testing tools.

Lab Made Fancy Colored Diamonds Introduction

​Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Rough Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Rough Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
