Lab Grown Colored Diamonds Description
Synthetic diamond is mainly produced by high pressure and high temperature (hPTP) and chemical vapor deposition (CVD) methods. And its quality is similar to natural diamond. Artificial diamonds are often used to process priceless jewelry.
Over the past decade, laboratory-made diamonds have received widespread attention because it allows for new applications of many diamonds that have previously been considered too difficult. Artificial rough diamond is an environmental protection product, 100% of which is free of conflict.
With the progress of human science and technology, scientists moved the natural diamond growth environment into the laboratory, simulated the whole growth environment of diamonds with high pressure and high temperature, and used gravel sized diamonds as seeds to grow. Diamonds grown in the laboratory are manufactured by advanced processes such as high pressure and high temperature (hPTP) and chemical vapor deposition (CVD).

Lab Grown Colored Diamonds 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.
