Pressure And High Temperature Technology
Rough Lab Grown Diamonds Description
Laboratory diamonds, known as synthetic diamonds. The lab grown diamonds is the product of the development of high
technology.
Artificial diamonds is more environmentally friendly and saves
labor costs. The biggest cost is production costs. The natural diamond and the synthetic diamond are all the same.
Hardness, crystal, refractive index and so on are exactly the same.
The main difference between them is the formation condition. One is
dug underground, and the other is produced by lab grown diamond
machines.
Making lab-grown diamonds in the laboratory is more sustainable.
The growth of laboratory rough diamonds can take a week or more
depending on the size and method. Scientists use common elements to
make lab-grown diamonds.
At present, there are two methods of artificial cultivation of
diamonds in the world: high temperature and high pressure method
and Chemical Vapor Deposition method. HPHT way is to use graphite on a huge machine, which smashes
diamonds with extremely high pressure and high temperatures, just
like when the earth formed natural diamonds. The high pressure high
temperature (HPHT) process turns graphite into diamond. In the CVD
method, scientists put diamond "seed crystals" into a chamber
filled with ordinary gas. When the gas is heated, they begin to
form a carbon layer on the seed crystals, allowing them to grow and
eventually form lab-grown diamonds.

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. Professionals will be able to discern
subtle contrasts in diamond inclusions grown and mined in the
laboratory.
