White Hpht Rough Lab Grown Diamonds Description
Laboratory diamonds, known as synthetic diamonds. At present, there
are two methods of artificial cultivation of diamonds in the world:
high temperature and high pressure method and chemical vapor
deposition method. These two kinds of diamond production methods
are different, the products are the same, known as artificial
cultivation diamond.
Are Lab Grown Diamonds the real diamonds?
Both the Lab Grown Diamonds and natural diamond cultivated in the
laboratory are pure carbon, which are in the same cubic crystal
form. Professionals can identify the differences between laboratory
diamond and natural diamond through high-tech equipment, but it
can't be done with naked eyes.
High pressure high pressure (HPHT) imitates the formation process
of natural diamond, puts seeds under great mechanical pressure, and
exerts great pressure and high temperature on ready-made carbon.
Seeds will quickly turn into diamonds with carbon lattice and grow
layer by layer in a few days until they reach the desired carat
weight.

White Hpht Rough Lab Grown Diamonds Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The 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 Lab Grown Diamonds and natural
diamonds?
There is no obvious difference between the 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.
