Rough Lab Grown Diamonds Description

1. What is cultivating diamond?
Diamond is cultivated in the laboratory, the advanced technology is used to simulate the environment of natural diamond formation in the equipment, and the diamond crystal is used as seed to induce diamond crystal growth. The physical and chemical properties of cultivated diamonds are the same as those of 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 and cultivate diamonds on the market: high temperature and high pressure method, referred to as HPHT; chemical vapor deposition, referred to as CVD.
Nowadays, the large carat cultivation diamond growth technology has realized the mass production of white, yellow, blue, green, purple red and other color cultivation diamonds. The color of white diamonds can reach D-E level and the clarity can reach vvs-si level.

2. Is it easy to distinguish cultivated diamond from natural diamond?

Many people have similar doubts: since diamonds can be cultivated artificially, can they be mixed with natural diamonds? If I want to buy natural diamonds, will I buy cultivated diamonds at the price of natural diamonds?
In fact, there is no need to worry about this. Now the quality inspection institutions use professional instruments to test the diamonds. By comparing the crystal shape, internal growth characteristics, inclusion characteristics, absorption spectrum, cathodoluminescence and other aspects of the tested diamonds, they can completely distinguish cultivated diamonds from natural diamonds. After all, natural diamonds are formed in a relatively stable environment deep underground for a long time. Natural diamonds have a long history, and the youngest diamonds are billions of years ago. However, it only takes a few weeks or even days to cultivate diamonds. There are subtle differences in the growth environment between the two, which can be distinguished by professional detection methods.
