1.30mm - 1.70mm Vvs Vs Def Color Loose Lab Grown Diamonds Round Cut
Loose Lab Grown Diamonds Description
Lab grown diamonds are diamonds grown in the laboratory using
machines. After polishing and cutting lab grown diamonds are no
different from natural diamonds. Both laboratory grown diamonds and
natural diamonds are real diamonds. The main chemical components of
laboratory-grown diamonds and natural diamonds are carbon.
At present, HTHP and CVD are the two main methods for making lab
grown diamonds.
High temperature and high pressure method (HTHP) uses graphite as
raw material, introduces suitable metal catalysts, such as Fe, Co,
Ni, Mn, Cr, etc., and can synthesize diamond at temperatures above
2000K and tens of thousands of atmospheres.
Chemical Vapor Deposition (CVD) is a method of decomposing raw
materials at high temperatures to produce active particles such as
carbon atoms or methyl groups, and depositing and growing a diamond
film on the substrate (substrate) under certain process conditions
Methods.
Both HPHT and CVD can make lab grown diamonds by lab grown diamond
machine. But people can distingush HPHT or CVD rough diamonds from
the lab grown rough diamond shape because HPHT and CVD methods use
different machine and technology to create diamonds.
At the beginning of 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.

Loose 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.
