Wholesale Yuda Crystal Synthetic Rough Uncut Diamond HPHT White
Rough Diamond For Loose Lab Diamond Making
Synthetic Rough Uncut Diamond Description
Synthetic diamond is mainly produced by chemical vapor deposition
(CVD) or high pressure high temperature (HPHT) methods which are
similar to natural diamond in quality. Synthetic diamond is often
used to process priceless jewelry, because it can be cut into a
variety of shapes and polished to achieve many different finished
diamonds.
Lab-Created diamonds have received much attention within the last
decade, because it allows many new applications of diamond
available that had previously been considered too difficult. And
Synthetic Rough Uncut Diamond is an Eco-Friendly product and 100%
conflict free.
With advances in human technology, scientists have moved the
environment of natural diamonds into the laboratory, using high
presure high temprature (HPHT) to simulate the entire growing
environment of the diamond, with gravel-sized diamonds as seeds and
grown.
Since diamonds can be cultivated artificially, can they be mixed
with natural 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 means.

Synthetic Rough Uncut Diamond 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.
