Lab Grown Rough Diamonds Description


Are the rough diamonds grown in the laboratory real diamonds?
The rough diamonds grown in the laboratory and the natural diamonds grown in the laboratory are pure carbon and have the same physical and chemical properties.

What is the difference between a lab-grown rough diamond and a natural diamond?

Because natural diamonds are formed in the natural environment, other elements are often mixed in during the process of its formation. These impurity elements change the energy band structure of the diamond, making some natural diamonds not completely transparent, but showing Out a specific color. Diamonds with different impurities have different colors. For example, some diamonds are a little pink, some are a little sky blue, and some are light yellow or golden yellow.

Both natural and laboratory-grown rough diamonds are produced with carbon components, which are transformed into scintillating cubic crystals. Although its chemical basis provides laboratories with the same optical properties as natural diamonds, the cultivation of laboratory diamonds is not inherently rare. Natural diamonds are formed by squeezing deep layers of the earth's crust. This is why all natural diamonds that will always exist are "produced" and make them rare in the world. In turn, the laboratory will grow diamonds, and the production of diamonds is unlimited.

It is difficult for ordinary people to distinguish the difference between man-made diamonds and natural diamonds with the naked eye. In fact, the difference between these two types of diamonds is so small that it is difficult to distinguish them even with scientific instruments. Under normal circumstances, X-ray fluorescence spectrometers and other equipment can be used to detect diamonds, but there is currently no fixed criterion that can distinguish man-made diamonds from natural diamonds, so this type of detection can only give some reference. opinion.

Moreover, in addition to making all kinds of diamond jewelry, diamonds can also be used to make precision instruments such as lasers and radars. Diamonds are often used even in physical research. For example, when American physicists are studying high-temperature superconducting materials recently , In order to get a pressure of several million atmospheres, two diamonds are opposed to each other to generate a huge pressure. Therefore, even if it is not used to manufacture luxury goods, artificial diamonds reduce the price of diamonds, which are also very beneficial for applications in industry and scientific research.

Lab Grown 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.
