Wholesale Yuda Crystal Synthetic Rough Uncut Diamond HPHT CVD 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.
