CVD Lab Grown Diamonds Description
Many people refer to Lab Grown Diamonds as 'fake' diamonds, but this is not accurate. The carbon based chemistry of Rough Lab Grown Diamonds means that they are actually "real" diamonds - unlike cubic zirconia or moissanite.
What is a lab-grown diamond?
Lab-grown diamonds after polishing and cutting are no different from natural diamonds.Carbon is the main element of natural and laboratory-grown diamonds.
The HPHT synthesis method is a more traditional diamond cultivation method that uses molten metal alloys such as iron (Fe), nickel (Ni) or cobalt (Co) to form diamonds.
The CVD synthesis method is a relatively new method of cultivating diamonds. The vacuum chamber is filled with carbon-containing gas. A carbon plasma is formed at the bottom of the vacuum chamber. The plasma is continuously deposited on the carbon bottom layer at the bottom of the pressure chamber. For several weeks, the resulting flake crystals usually have black rough edges, and the crystals often appear brown, but they can be removed by heat treatment.
Many people have similar worries: since diamonds can be created in lab, can they be mixed with natural diamonds? If I want to buy natural diamonds, will I be cheated by using the price of natural diamonds to buy lab diamonds?
With professional equipment, the comparison of the color, crystal shape and crystal surface characteristics, internal inclusion characteristics, absorption spectrum and ultraviolet fluorescence characteristics of the tested diamonds can "completely distinguish the artificially cultivated diamonds from the natural diamonds". After all, natural diamond crystals were formed billions of years ago, while artificially cultivated diamonds can only be formed in a few days. There is no difference between the two, and it can be completely distinguished by professional testing tools.

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.
