Synthetic Colored Diamonds Description
What is laboratory diamond?
Laboratory diamond, also known as laboratory made diamond, synthetic diamond. Like natural diamonds, laboratory diamonds are also real diamonds. Because laboratory diamonds have the same chemical, physical and optical properties as mining diamonds. Carbon is the main chemical component of natural diamonds and laboratory diamonds. When people observe with naked eyes, it is impossible to distinguish between the diamonds produced in the laboratory and the diamonds mined. The main difference between the two is the environment in which they grow.
Laboratory grown diamonds are sometimes called CVD diamonds or HPHT diamonds. The reason is that CVD and HPHT are two ways to make diamonds.

Synthetic 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.
