Rectangular Long Shape 3carat 4carat 5carat CVD Lab Made Diamond
For Making Fancy Cut Cvd Diamond
CVD Lab Grown Diamonds Description
The laboratory cultivating diamonds uses advanced technology to
simulate the formation conditions of natural diamonds under the
earth's crust. This formation process is the main factor that
distinguishes laboratory diamonds from natural diamonds. The
physical and chemical properties of laboratory-grown diamonds and
natural diamonds are exactly the same as those of natural diamonds.
Is there any difference between laboratory-grown diamonds and
natural diamonds?
We can distinguish from the angle of formation method, price and
appearance quality.
The first is the formation conditions. Natural diamonds are
composed of carbon atoms and are formed after years of extreme high
temperature and pressure deep underground, while laboratory-grown
diamonds are grown in the laboratory using equipment through a
chemical process.
The second is the price difference. Lab-grown diamonds can be
mass-produced, so the price is cheaper than natural diamonds.
The third is appearance quality. Natural diamonds are formed
according to the natural environment, so their quality cannot be
controlled. The quality of cultivated diamonds can be controlled
artificially by the growth process.
From the above three aspects, Laboratory-grown diamonds undoubtedly
provide a choice for people who like to wear diamond jewelry.
Because laboratory-grown diamonds and natural diamonds are real
diamonds.
In the laboratory, there are two main processes for the manufacture
of lab grown rough diamonds. The first one is the high-pressure
high-temperature method (HPHT), The second one is chemical vapor
deposition (CVD).
HTHP: 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.
CVD: 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

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.
