Lab Grown Rough Diamond Description
Synthetic diamonds are mainly produced by chemical vapor deposition
(CVD) or high pressure and high temperature (HPHT) methods, and
their quality is similar to that of natural diamonds. Artificial
diamond is often used to processing priceless jewelry, it can be
cut into various shapes, and polishing for many different kinds of
diamond products.
In the past ten years, manufacture diamond lab has received the
widespread attention, because it allows a lot of people think are
difficult to before the new diamond applications. Synthetic diamond
is a kind of environmental protection product, 100% without
conflict.
With the progress of human technology, scientists have to transfer
natural diamond to the laboratory environment, the use of high
pressure high temperature (HPHT) simulation of the diamond growth
environment, the size of the diamond gravel as seeds to grow.
Nowadays, more and more companies are engaged in the manufacture of
artificial diamonds. Many countries and regions are in production
for jewellery and industrial use of artificial diamond.
Since diamonds can be grown artificially, can they be mixed with
natural diamonds?
By measurement of the use of professional equipment, the color of
the diamond, crystal shape, crystal surface characteristics,
internal inclusion and, comparing the absorption spectrum and
ultraviolet fluorescence characteristics can be fully distinguish
artificial cultivation of diamond and natural diamond. After all,
natural diamond crystals formed in the billions of years ago, but
artificial diamond can only be formed in a few days. There is no
difference between the two, through professional testing methods
can be distinguished.

Lab Grown Rough Diamond Introduction
Natural diamonds are created by nature, is the result of the
billions of years of high temperature and high pressure formation.
Laboratory-grown diamonds are usually produced in a lab for several
weeks. Both on the chemistry of the difference is the same.
So how do you distinguish between laboratory cultivation of diamond
and natural diamond?
There is no discernible difference between lab-grown diamonds and
natural diamonds. Even professional gemologists also need special
equipment to identify them. By magnifying, professionals will be
able to recognize in the lab, growth and production of diamond
inclusions nuances.
