CVD Lab Grown Diamonds Description
What is a laboratory rough diamond?
First of all, from a physical point of view, diamond is a carbon
elemental crystal 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.
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.
Generally speaking, Lab Grown Diamonds grown in the laboratory are
almost no different from natural diamonds, and it is difficult to
distinguish them with scientific instruments. In essence, Lab Grown
Diamonds and natural diamonds are actually a kind of thing, but
they are produced in different ways.

CVD 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 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.
