Synthetic Rough Uncut 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, the laboratory manufacture of diamond has received the widespread attention, because it allows many deemed too difficult before the new application of diamond. Synthetic diamond is a kind of environmental protection product, 100% without conflict.
With the progress of human technology, scientists have will be transferred to the laboratory environment of natural diamond, using high pressure high temperature (HPHT) to simulate the growth environment of diamonds, diamond the size of gravel as seed and grow.
Since diamonds can be artificial cultivation, so they can be mixed with natural diamond?
Using professional equipment, to be measured by the color of the diamond, crystal shape, crystal surface features, internal inclusion, absorption spectrum and ultraviolet fluorescence characteristics of contrast, can be completely to distinguish the artificial cultivation of diamond and natural diamond. After all, natural diamond crystals were formed billions of years ago, whereas cultured diamonds can only form in a matter of days. There is no difference between, through the professional test method can distinguish completely.

Synthetic Rough Uncut Diamond Introduction
Natural diamonds are created by nature, the result of billions of years of high temperature and pressure. Laboratory of rough diamond is produced in the laboratory, usually need a couple of weeks. Both on the chemistry of the difference is the same.
So how do you distinguish between rough laboratory diamond and natural diamond?
Synthetic diamond single crystal or polycrystalline. Single crystal gravel can be used for applications with special requirements. The easily recognized cubic or cubic octahedral shape reflects the characteristic crystal structure of diamond.
Unprocessed laboratory production of diamond and natural diamond had no obvious difference. Even professional gemologists need special equipment to identify them. By magnifying, professionals will be able to recognize in the lab, growth and production of diamond inclusions nuances.
