Rough Lab Grown HPHT Synthetic Diamond Description
Lab grown diamonds are made in the laboratory. There are two main methods to make Rough Lab Grown HPHT Synthetic Diamond: one is high pressure and high temperature method (HPHT), the other is chemical vapor deposition method (CVD).
HPHT(High Pressure and High Temperature) method is the primary method used to grow lab grown rough diamonds. Currently the world's popular HPHT synthetic diamond making equipment mainly includes two side top, six side top and bar split sphere or improved split sphere.
Since diamonds can be created by equipment, will people be cheated by using the price of natural diamonds to buy lab 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 lab grown diamonds from the natural diamonds. After all, natural diamonds were formed billions of years ago, while lab grown 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 tools.

Rough Lab Grown HPHT Synthetic 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.
