Lab Grown Rough Diamonds Description
The diamonds made in the laboratory, also known as engineering or cultured diamonds, grow in a highly controlled laboratory environment. With advanced technology, they reproduce the natural conditions for the formation of diamonds under the mantle and crust. These synthetic diamonds are made up of actual carbon atoms, which are arranged in the unique crystal structure of diamonds. Because they are made of the same material as natural diamonds, they have the same optical and chemical properties.
The diamonds in our lab grow from the tiny carbon seeds of existing diamonds. Advanced technology - either extreme pressure and heat or a special deposition process - mimics the natural methods of diamond formation. Laboratory grown fancy colored diamonds are formed when a small amount of specific trace elements are present in the diamond growth stage, just like in nature. In white and colored laboratory diamonds, the exact composition of trace elements may be different from that of natural diamonds. Laboratory diamonds can only be distinguished from natural diamonds by special equipment, which can detect trace elements and subtle differences in crystal growth.
The diamonds produced in our laboratory can now be easily bought in all kinds of colorless diamonds. Cultured diamonds are also available in fancy colors and are considered to be very rare in nature, including the popular colorful Fancy Yellow. Compared with natural color diamond, the price of color diamond produced in laboratory is relatively reasonable.
Diamonds manufactured in our laboratory exhibit the same physical, chemical and optical properties as natural diamonds, and exhibit the same flame, flicker and flash. With a jewelry magnifying glass, it is almost impossible to distinguish man-made diamonds from natural ones. Laboratory diamonds may exhibit different trace elements than natural diamonds and do not affect the appearance of diamonds. Only by testing with special equipment can laboratory diamonds be distinguished from natural diamonds. Laboratory produced diamonds available for purchase should always carry gemstone certification to confirm that they are laboratory produced.

Lab Grown Rough 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.
