Rough Lab Grown Diamonds Description
What is a lab-grown diamond?
Lab diamonds are real diamonds. Lab-grown diamonds after polishing
and cutting are no different from natural diamonds.
The environment in which diamonds grow in the laboratory is
different from that of natural diamonds. Natural diamonds come from
the earth, and laboratory-grown diamonds do not grow on the earth,
but grow in the laboratory. Similarly, laboratory-grown diamonds are as hard as natural
diamonds. Both lab diamonds and natural diamonds can emit the same light,
have the same color and clarity, and can have the same size and
shape.
Carbon is the main element of natural and laboratory-grown
diamonds. The only chemical difference between laboratory-grown
diamonds and natural diamonds is that most natural diamonds contain
trace amounts of nitrogen, while laboratory diamonds do not. The
lack of nitrogen is a way for gemologists to identify lab diamonds
from natural diamonds.
Beginning in the 1930s, scientists discovered that certain types of
diamonds have similar characteristics, so they divided diamonds
into two categories based on the difference in transparency under
ultraviolet radiation: Type I and Type II. Subsequently, the
scientists further divided type I and type II diamonds into two
sub-categories: type Ia, type Ib, type IIa and type IIb through the
arrangement of carbon atoms and impurity atoms in the diamond
structure.
By 1959, scientists discovered that the main chemical impurity in
diamonds was nitrogen, which is contained in type I diamonds, but
not contained in type II diamonds. Using infrared spectroscopy can
quickly determine the type of diamond.
Most natural diamonds are type Ia. Type Ia diamonds contain
abundant nitrogen in clusters or pairs. Type Ib diamonds contain
unpaired or clustered scattered nitrogen atoms, which are rare in
natural diamonds. Type IIa diamond contains almost no nitrogen. The
IIb diamond contains boron atoms. Most synthetic diamonds are of type Ib, IIa and IIb.

Rough Lab Grown Diamonds Introduction
Lab Grown Diamond is a crystal 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.
