White Synthetic Rough Diamond Description


Synthetic diamonds exhibit the same physical, chemical and optical properties as natural diamonds, and exhibit the same flame, flicker and flash. Under magnifying glass, it is almost impossible to distinguish man-made diamonds from natural diamonds. Laboratory made diamonds may exhibit trace elements different from natural diamonds, which do not affect the appearance of diamonds. Only by using special equipment for testing, can we distinguish between laboratory grown diamonds and natural diamonds. Laboratory diamonds available for purchase should always carry gemstone certification to confirm that they are laboratory produced.


Laboratory diamonds also known as laboratory made diamonds, synthetic diamonds, artificially diamonds or cultivated diamonds. Because they are actually made up of carbon atoms, the lab grown diamonds show the same chemical and optical properties as natural diamond crystals produced by natural geological processes. The price of synthetic diamonds is generally lower than that of natural diamonds.

Diamonds made in the laboratory are made by copying the manufacturing process of natural diamonds.

Natural diamonds are grown by high temperature and high pressure. After millions of years, carbon atoms are transformed into beautiful and charming gemstones, which we call diamonds.

Diamonds made in the laboratory grow in the same way, only through an artificial process that takes weeks, not millions of years.

Synthetic diamonds start with a small piece of diamond, which is called diamond seed. The seed is sealed in a special chamber designed to simulate conditions inside the crust.

The surface of the seed crystal is coated with pure carbon, which will eventually be transformed into synthetic diamond with the same chemical properties as natural diamond.

White Synthetic Rough Diamond 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 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. Professionals will be able to discern subtle contrasts in inclusions between lab grown and mined diamonds
