Hpht Rough Lab Grown Diamond Description


Lab grown diamond, also know as synthetic diamond, lab created diamond and man made diamond, is real diamond. Lab diamond and natural diamond both have same chemical and physicial properties.


HTHP synthetic diamonds are often cubes, octahedrons, and the combination of the two; the color is often yellow, yellowish brown, and the internal features such as colored bands and metal inclusions are common. The unmelted metal inclusions are needle-shaped, flake-shaped, and small columnar. Or irregular appearance with metallic luster, which makes synthetic diamonds magnetic.

Synthetic diamonds usually have no fluorescence under long-wave ultraviolet, and often have yellow, green-yellow, orange-yellow fluorescence under short-wavelength. Synthetic diamonds have characteristic banding under ultrashort-wave ultraviolet or cathode rays. Different growth areas show different colors of fluorescence.

Hpht Rough Lab Grown 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. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
