HPHT Cvd Polished Diamonds Description
Lab diamonds are real diamonds. Carbon is the main element of natural and laboratory-grown diamonds. Lab-grown diamonds are diamonds grown in the laboratory using equipment that simulate the growth environment of natural diamonds. The chemical and physical properties of synthetic diamonds are same as natural diamonds in terms of hardness, thermal conductivity, and strength. Therefore, synthetic diamonds have the same hardness and durability as natural diamonds, After polishing and cutting lab-grown diamonds are same as natural diamonds. they have the same brightness and fire.
Can we distinguish between laboratory grown diamonds and natural diamonds?
Yes it is. However, only diamond professionals can identify the difference between laboratory grown diamonds and natural diamonds by using professional diamond identification equipment.
HTHP and CVD are the two main methods for making laboratory-grown diamonds.
High temperature and high pressure method (HTHP) uses graphite as raw material. HPHT diamonds are manufactured at a pressure of 5-6 GPA (approximately the pressure produced by a commercial jet landing on a human fingertip) and a temperature of 1300-1600°C.
CVD diamonds come from various gases, such as methane. They are stored in a vacuum chamber, which decomposes the molecules of the gas, and then these molecules gather on the pre-existing diamond seeds.

HPHT Cvd Polished 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.
