Lab Grown HPHT Rough Diamonds Description
There are two main processes to make artificial diamond: one is
high pressure and high temperature method (HPHT), the other is
chemical vapor deposition method (CVD).
Will artificial diamonds be confused with natural diamonds?
Many people have similar doubts: since diamonds can be cultivated
artificially, 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 artificial diamonds?
There is no need to worry about this. In fact, the artificial
cultivation of diamonds is divided into different levels and
different uses. Industrial grade diamonds are widely used, from
well-known cutting to runway construction to decoration. However,
the production difficulty of gem grade diamonds is very different
from that of industrial grade diamonds. If the previous gem grade
diamonds were still in a rough state, now the diamonds have been
completely transformed and can be put on the elegant stage.
In the past, gem quality diamonds were artificially cultivated
because they contained many impurities, and they could even be
adsorbed by iron absorption stone. Is it a relief for those who are
afraid of buying the wrong diamonds? You don't have to worry about
it. It's very difficult for you to distinguish the gem grade
artificial diamonds with the iron absorption stone because of the
improvement of the craft level. But don't worry. 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 means.

Lab Grown HPHT Rough 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.
