Rough Lab Grown Diamonds Description
Lab grown diamonds are the diamonds grown in the laboratory. People use advanced equipment to mimic the environment of natural diamond formation. Diamond crystals are used as seeds to induce the growth of diamond crystals. The physical and chemical properties of man-made diamonds are exactly the same as those of natural diamonds. At present, high quality synthetic diamonds are mainly used in jewelry.
Currently there are two main methods to make lab grown diamonds. They are chemical vapor deposition (CVD) and high pressure high temperature (HPHT) methods.
What's the difference between laboratory diamonds and simulated diamonds? Unlike laboratory grown diamonds, simulated diamonds are not real diamonds. Although the shape of simulated diamond is similar to that of real diamond, it is made of seed materials such as glass or cubic zirconia. This makes it impossible for silicon carbide and other simulated diamonds to have the hardness and optical properties of diamond grown in laboratory. Over time, they are more likely to wear out and lose luster.
Can we distinguish between laboratory diamonds and natural diamonds? yes. However, only diamond professionals can identify the difference between laboratory grown diamonds and natural diamonds by using professional diamond identification equipment.

Lab Grown Diamonds Introduction
Natural diamonds are created by nature and are the result of high temperature and high pressure formed over billions of years. The lab grown diamonds are produced in the laboratory, usually in a few weeks. The chemical composition of both is same.
So how do you distinguish between lab grown diamonds and natural diamonds?
There is no obvious difference between the 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.
