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 Methods.

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.
