Rough Lab Grown Diamonds Description
Laboratory-grown diamonds have many different names: lab diamonds,
lab-made diamonds, man made diamonds, and even synthetic diamonds.
These names indicate that cultivated diamonds are artificially
created in laboratories or factories, rather than naturally formed
or mined from the ground. To create lab grown diamonds, scientists
use advanced technology to simulate the formation conditions of
natural diamonds under the earth's crust. This formation process is
the main factor that distinguishes lab diamonds from natural
diamonds.
Since the physical and chemical properties of laboratory-grown
diamonds and natural diamonds are exactly the same as those of
natural diamonds, can people distinguish between the two?
The answer is yes. In fact, in terms of shape, rough lab grown
diamonds and natural diamonds usually have different shapes. Due to
different formation conditions, natural diamonds usually are
octahedral crystals, that is, eight equilateral triangular crystal
faces, while lab grown rough diamonds usually grow into crystals
that contain both octahedrons and cubes, that is, six square
crystal faces. Therefore, it can be easily distinguished from the
appearance. Gem-quality laboratory-grown diamonds are usually
manufactured by two technologies, HPHT and CVD. Due to different
technical principles, the shapes of diamonds grown in HPHT and CVD
laboratories are also different. The shape of HPHT diamond is
usually a combination of cube and octahedral surface, while the
shape of CVD diamond has no octahedral surface at all. The cubic
crystal face grows faster than the octahedral crystal face.
However, it is difficult to distinguish between polished
laboratory-grown diamonds and natural diamonds with the naked eye.
Professionals can rely on professional testing equipment to
distinguish them.

Rough Lab Grown Diamonds Introduction
Rough Lab Grown Diamond is a polycrystalline diamond made of diamond crystals with a
diameter of 10 to 30 nanometers. In the early stage, man-made
diamonds showed a light color of sugar due to the nitrogen atoms in
the air entering into the diamond crystal. Through the improved
production method of scientists, there is no difference between
man-made diamonds and natural diamonds in appearance now.
