Lab Grown HPHT Rough Diamonds Description


There are two main processes to make artificial diamond: one is high pressure and high temperature method (HPHT), the other is chemical vapor deposition method (CVD).

Will artificial diamonds be confused with natural diamonds?

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 be cheated by using the price of natural diamonds to buy artificial diamonds?

There is no need to worry about this. In fact, the artificial cultivation of diamonds is divided into different levels and different uses. Industrial grade diamonds are widely used, from well-known cutting to runway construction to decoration. However, the production difficulty of gem grade diamonds is very different from that of industrial grade diamonds. If the previous gem grade diamonds were still in a rough state, now the diamonds have been completely transformed and can be put on the elegant stage.

In the past, gem quality diamonds were artificially cultivated because they contained many impurities, and they could even be adsorbed by iron absorption stone. Is it a relief for those who are afraid of buying the wrong diamonds? You don't have to worry about it. It's very difficult for you to distinguish the gem grade artificial diamonds with the iron absorption stone because of the improvement of the craft level. But don't worry. 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 means.

Lab Grown HPHT Rough 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.
