Lab Grown HPHT CVD Diamonds Description
CVD is an acronym for chemical vapour deposition and HPHT is an acronym of High Pressure High Temperature.Laboratory diamonds are generally produced by chemical vapor deposition (CVD) or high pressure and high temperature (HPHT) processes and are of similar quality to natural diamonds.
Laboratory diamond is a diamond cultivated by machine in the laboratory. After polishing and cutting, laboratory grown diamonds are no different from natural diamonds. The diamonds produced in the laboratory and natural diamonds are real diamonds. The main chemical composition of diamonds and natural diamonds produced in the laboratory is carbon.
At present, high temperature and high pressure method and chemical vapor deposition method are two main methods to prepare laboratory diamond.
High temperature and high pressure method (HTHP) uses graphite as raw material and introduces appropriate metal catalysts, such as Fe, Co, Ni, Mn, Cr, etc., which can synthesize diamond at the temperature of more than 2000K and tens of thousands of atmospheres.
Chemical vapor deposition (CVD) is a method of decomposing raw materials at high temperature to produce active particles such as carbon atoms or methyl groups, and depositing and growing diamond films on the substrate (substrate) under certain process conditions.
HPHT and CVD can produce laboratory diamond through laboratory diamond forming machine. However, due to the different machines and technologies used in the production of diamonds by HPHT and CVD, people can distinguish the diamonds produced by HPHT and CVD from those produced in the laboratory.
However, gem grade diamonds produced in the laboratory can now be produced under natural conditions, using high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) technology to simulate the production of natural diamonds in the laboratory in a few weeks.

Characteristics Of Lab Grown HPHT CVD Diamonds
The diamond is cultivated in the laboratory. People use advanced equipment to simulate the environment of natural diamond formation. Diamonds produced in the laboratory are usually produced in the laboratory for several weeks. Natural diamonds are created by nature and the result of billions of years of high temperature and high pressure. The chemical differences between the two are the same.
So how to distinguish between laboratory grown diamonds and natural diamonds?
There is no significant difference between laboratory cultured diamond and natural diamond. Even professional gemologists need special equipment to identify them. Through amplification, professionals will be able to identify subtle differences in the growth and production of diamond inclusions in the laboratory.

In the past decade, synthetic diamond has received wide attention because it allows many new applications of diamond. Lab-grown diamond is an environmentally friendly product with pollution-free technology and no environmental pollution.
From a scientific point of view, synthetic diamond and natural diamond are exactly the same. The only difference is that they are formed in different positions.
