Hpht Single Crystal Diamonds Description
Lab diamonds are real diamonds. Carbon is the main element of
natural and laboratory-grown diamonds. The chemical and physical
properties of synthetic diamonds are same as natural diamonds in
terms of hardness, thermal conductivity, and strength.
High temperature and high pressure (HPHT) and chemical vapor
deposition (CVD) are the two most commonly used growth methods in
synthetic diamonds industrial. High temperature and high pressure
exert intense heat (about 1500 degrees Celsius, or 2700 degrees
Fahrenheit) and pressure (1.5 million pounds per square inch) on
the diamond seed and the carbon atoms surrounding it. Chemical
vapor deposition, on the other hand, uses less heat and pressure,
but introduces a mixture of chemical gases, which decomposes and
hardens into crystalline carbon atoms.
Diamond has always been favored by the scientific and industrial
circles, and is widely used in optics, semiconductor, oil
exploration and other fields. Diamond is an excellent optical
material with high transmittance from X-ray to microwave, high
hardness, high thermal conductivity, high chemical stability and
low coefficient of expansion. Also diamond is an ideal
semiconductor material with wide band gap, high carrier mobility,
high breakdown voltage and high thermal conductivity.

Hpht Single Crystal 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.
