DEF VVS VS Lab-Created 1.0ct 1.5ct 2.0ct HPHT Lab Grown Diamonds
HPHT Lab Grown Diamonds Description
The Lab Grown Diamonds are produced in the laboratory. The
laboratory uses advanced technology and equipment to reproduce the
formation enviornment of natural diamonds. By using fine diamond
seeds to induce natural diamond crystallization, Lab Grown Diamonds
with the same physical, chemical and optical properties as natural
diamond can be cultivated on the ground. Lab Grown Diamonds are
real diamonds.
Lab Grown Diamonds are 100% real diamonds and 100% eco-friendly
diamonds. It's very cost effective and more affordable.
HPHT stands for high pressure and high temperature. In order to
grow high performance high temperature diamond, a small diamond
seed was put into carbon, diamond is made of carbon. Diamond seeds
are exposed to extreme heat and pressure to replicate diamonds in a
natural way. They grow underground. Diamond seeds exposed above
1100 degrees, pressure about 1.5 million Pounds per square inch.
The carbon melts around the seeds and forms diamonds. Then it cools
and the diamond forms.
Chemical vapor deposition (CVD) is a method to grow diamond from
hydrocarbon gas mixture. The flexibility and simplicity of CVD
devices explain the popularity of CVD growth in laboratory
research. The advantages of CVD diamond growth include the ability
to grow diamond on large area and different substrates, as well as
the fine control of chemical impurities and properties of the
diamond.
The growth of CVD involves the preparation of substrates, injecting
different amounts of gases into a chamber and energizing them. The
substrate preparation includes selecting suitable materials and
crystal orientation; When cleaning, diamond powder is often used to
grind non diamond substrate; Optimized substrate temperature (about
800 ℃) In the growth process, through a series of test run. These
gases usually include a carbon source, usually methane, and a
typical ratio of 1:99 hydrogen. Hydrogen is essential because it
selectively corrodes non diamond carbon. These gases are ionized
into chemically active radicals in the growth chamber by microwave
power, hot filament, arc discharge, welding torch, laser, electron
beam or other methods.

HPHT 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.
