CVD Lab Grown Diamonds Description
What is cultivating diamond?
The physical and chemical properties of cultivated diamonds are the same as natural diamonds. With the progress of science and technology, the purity and color of cultivated diamonds are getting higher and higher, which can be used for jewelry.
At present, there are two main methods to produce lab grown diamonds: HPHT and CVD methods.
Nowadays, the color of white lab grown rough diamonds can reach D-E level and the clarity can reach vvs-si level.
Since diamonds can be cultivated artificially, can they be mixed with natural diamonds?
In fact, there is no need to worry about this. By comparing the crystal shape, internal growth characteristics, inclusion characteristics, absorption spectrum, cathodoluminescence and other aspects of the tested diamonds, lab grown diamonds can completely be distinguished from natural diamonds. After all, natural diamonds are formed in a relatively stable environment deep underground for a long time. However, it only takes a few weeks or even days to make lab grown diamonds. There are subtle differences in the growth environment between the two, which can be distinguished by professional detection methods.
Generally speaking, Lab Grown Diamonds grown in the laboratory are almost no different from natural diamonds, and it is difficult to distinguish them with scientific instruments. In essence, Lab Grown Diamonds and natural diamonds are actually a kind of thing, but they are produced in different ways.

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 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.
