HPHT Rough Lab Grown Diamond Description
Rough Lab Grown Diamond made in the laboratory, not mined from the earth. Rough Lab Grown Diamond are not fakes, they are not cubic zircons, they are not crystals. They are identical in chemical composition to natural diamonds.
Although scientists have been using this process since the middle of 1900, the diamonds originally made are pumpkin colored. It is only in recent years that scientists have found a way to produce the most familiar white diamond. There are two ways to make Rough Lab Grown Diamond. One is to use extreme high pressure and high temperature to imitate the natural diamond process and dissolve carbon into diamond seeds; Another method is similar to 3D printing, in which carbon is layered on the crystal seeds. Then, put the seeds in a peculiar diamond microwave oven, inject carbon gas into the microwave oven and stick it on the seeds to slow down the growth of the seeds.
Perhaps not surprisingly, Rough Lab Grown Diamond are controversial in the gem world. The cost of laboratory training is quite high. We bring the best quality laboratory grown diamonds through excellent cutting and polishing procedures. We believe that the diamond cultivated in the laboratory is also a lifetime diamond. Some people say that the plants in the laboratory can grow at any time in the laboratory, just like the earth. The diamonds mined have been mined for many years, and they are still mined every day and put on the market every day. We say that the diamonds mined by the earth will never stop mining, and the diamonds planted in the laboratory will never stop growing in the laboratory with the latest technology.

HPHT Rough Lab Grown 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.
