Rough Lab Grown Diamonds Description
What is a laboratory rough diamond?
First of all, let's talk about diamonds. From a physical point of
view, diamond is a carbon elemental crystal (crystal, which has a
fixed shape and melting point), and its composition is the same as
that of coal and graphite. However, although the coal and graphite
we see in our lives are all black, diamonds are not black at all.
They are transparent. This is because diamond, as a crystal, has a
special energy band structure for the electrons inside. This
structure determines that it will not absorb the energy of visible
light, so visible light can pass through the entire diamond, making
the diamond appear transparent.
Natural diamonds generally come to the surface of the earth during
a volcanic eruption. At first, they were formed under the high
temperature and high pressure environment deep in the earth, and
then they were brought to the surface of the earth by magma. Most
diamonds are formed almost as old as the age of the earth.
Lab-grown diamonds have been used in industry for more than 50
years, but in the past ten years, their quality and price have
improved significantly, which means that these lab-grown diamonds
can now be used in jewelry. Changing the "recipe" in the laboratory
also means that the diamonds grown in these laboratories can also
have different colors, including beautiful blues and pinks.
What are the advantages of developing diamonds in the laboratory?
Lab-grown diamonds can shine like natural diamonds.
Lab-grown diamonds can be mass-produced within a few weeks. As a
result, laboratory-grown diamonds are much cheaper than natural
diamonds of the same size and quantity.
In addition to colorless gems, laboratory-grown diamonds also
provide a range of rare and expensive colors in their natural form.

Rough Lab Grown Diamonds 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.
