Difference Between Synthetic Diamond and Natural Diamond

There is a difference between synthetic diamond and natural diamond all the time, because synthetic diamond is formed in a short period of time, but the age of natural diamond is very long.

The oldest natural diamond is about 4 billion years old, and the youngest is about 1 billion years old; And synthetic diamond formed in a short time, is like a budding boy compared with the old man of 1 billion years old. The internal growth structure and internal stress of synthetic diamond, are quite obvious, and experienced experts can check them through specialized instruments. There is a kind of domestic diamond tester, which can identify synthetic diamond just in a second. What’s more, the instrument can detect synthetic diamond even they are in a transparent box or plastic bag.

There is a way that is the most easy to learn and the most intuitive, and we can see the growth of the texture of synthetic diamond. The growth structure of chemical vapor deposition method is just like cakes with thousand layers. As long as the growth can be controlled well, we are couldn't identify the transverse structure with the naked eye. But if we use the specific energy of light to illuminate, the samples will have a luminous effect, and the luminous effect can make the growth of the transverse structure fully displayed.

In fact, there are some other characteristics about synthetic diamond. For example, under ultraviolet light, natural diamonds will have blue or blue and white fluorescent, but old-fashioned CVD synthetic diamond will be shown red orange silverlight. The new-style diamond will be shown turquoise or blue purple silverlight, but we can't say this approach is identified.

And of course, we can also distinguish through some other ways. For example, infrared spectral analysis technology and laser Raman spectroscopy can both detect synthetic diamond. If you have great synthetic diamond suppliers, such as Boshi Superhard Material Co.,Ltd., Yuzhou He Hui Superabrasives Co.ltd., Xinren Superabrasives Co,.limited, Beijing Xin Bai Bentley Superhard Materials Co., Ltd., Jinxin Abrasives Co.,ltd., etc., you do not need to worry about that as they offer not only high quality synthetic diamonds but also professional services.
