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.
