CVD Lab Grown Diamonds Description


What is lab grown diamond?
Lab-grown diamonds are grown in the laboratory. People use advanced equipment to simulate the environment in which natural diamonds are formed.
This formation process is the main factor that distinguishes lab-created diamonds from mined diamonds. Lab-grown diamonds can be mass-produced within a few weeks. As a result, laboratory-grown diamonds are much cheaper than natural diamonds of the same size and quantity.
Since the physical and chemical properties of laboratory-grown diamonds and natural diamonds are exactly the same as those of natural diamonds, can one distinguish between the two?
The answer is yes. In fact, in terms of shape, rough lab created diamonds and natural diamonds usually present different shapes. Due to different formation conditions, natural diamonds usually present octahedral crystals, that is, eight equilateral triangular crystal faces, while cultivated diamonds usually grow into crystals that contain both octahedrons and cubes, that is, six square crystal faces. Therefore, it can be easily distinguished from the appearance.
At present, there are two main methods for cultivating diamonds in the laboratory, namely, high temperature and high pressure method and chemical vapor deposition synthesis method. Both of these mainstream methods are currently in mass production.
The synthetic diamond is the product of the development of high technology. Synthetic diamonds is more environmentally friendly and saves labor costs.

CVD 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 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.
