Product Description

Rough Lab Grown Diamonds Description


Although laboratory-grown diamonds are formed in different environments and conditions from natural diamonds, both natural diamonds and lab diamonds are crystals composed of pure carbon, and the physical properties, chemical properties, crystal structure and optical properties of the two are same. Lab rough diamonds are grown in the laboratory by imitating the high temperature and high pressure environment of diamonds deep in the earth.

Due to the different growth environments of laboratory-grown diamonds and natural diamonds, the shape, clarity and color of the diamond will be different, so the price will also be different. However, the price of lab grown diamonds is still relatively low compared to  mined diamonds.

Natural diamonds are usually formed millions even billions of years ago, 160 kilometers or more deep underground, and were brought to the surface in volcanic eruptions many years later. Since the formation conditions of natural diamonds are very strict and the formation period is also very long, natural diamonds are perfectly octahedrons.

Because the laboratory environment species currently cannot reach the ultra-high temperature required for the formation of natural diamonds, and the cultivation time is relatively short, synthetic diamonds often exhibit octahedral and cubic shapes.

At present, there are two main methods for cultivating diamonds in the laboratory, namely, high temperature and high pressure method and chemical vapor deposition method. Both of these mainstream methods are currently in mass production. Because the two methods use completely different equipment and manufacturing principles, the laboratory-grown diamonds produced by the two methods are completely different in shape.

Whether laboratory-grown diamonds or natural diamonds, loose diamonds after cutting and polishing can not be distinguished by the naked eye. It can be detected only with the help of professional equipment.

Rough Lab Grown Diamonds Introduction


Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The 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.
