Synthetic Rough Uncut Diamond Description

 

Synthetic diamond is mainly produced by chemical vapor deposition (CVD) or high pressure and high temperature (HPHT), and its quality is similar to that of natural diamond. The molecular structure of the synthetic diamond is not the full octahedral structure of natural diamond, but a complex structure, phosphorescence is produced. With the maturity of artificial diamond production technology, its cost is lower, and can produce a variety of colors of diamonds and jewelry market best-selling.

Scientists have put natural diamond moved to the laboratory environment, high pressure high temperature (HPHT) was used to simulate the diamond growth environment, the size of the diamond gravel as seeds to grow.

Since diamonds can be grown artificially, can they be mixed with natural diamonds?

By measurement of the use of professional equipment, the color of the diamond, crystal shape, crystal surface characteristics, internal inclusion and, comparing the absorption spectrum and ultraviolet fluorescence characteristics can be fully distinguish artificial cultivation of diamond and natural diamond. After all, natural diamond crystals formed billions of years ago, whereas synthetic diamonds can only form in a matter of days. There is no difference between the two, through professional testing methods can be distinguished.

The molecular structure of the synthetic diamond is not the full octahedral structure of natural diamond, but a complex structure, phosphorescence is produced. With the maturity of artificial diamond production technology, its cost is lower, and can produce a variety of colors of diamonds and jewelry market best-selling.

From a scientific point of view, synthetic diamond and natural diamond exactly the same, the only difference is that the formation of their location.

Laboratory developed in every aspect is a real diamond, diamond is the same as the mine drill of chemistry, physics, atomic, optical, and all properties; Diamond was generated and cultivated by artificial method to simulate the crystal characteristics of ore drill. Laboratory-grown diamonds have five advantages. Technology: (1) innovation laboratory training under the action of the diamond is in a high-tech instrument, simulated mine of natural environment, generate diamond environment needed for the drill. Lab-grown diamonds are created by the best scientists, professional engineers and skilled technicians, and are the crystallization of the wisdom of human science and technology. (2) excellent quality: laboratory cultivation idea of diamond on the premise of environmental protection, has not given up the pursuit of the quality and value. Adopt the same 4C grading standard as mine diamond, and have the appraisal certificate issued by the international third party diamond appraisal organization. (3) green earth: cultivating diamond is the most outstanding scientists, professional engineers and skilled technical personnel to create, only the use of renewable energy, such as power and solar energy, and use the greenhouse gas methane as a source of carbon, destructive rather than a large mechanical mining. Experts predict that the most important invention of this century will be lab-grown diamonds. Cheap lab-grown diamonds could replace silicon as a semiconductor, bringing human technology to another world. ⑤ Price advantage: lab-grown diamonds are more popular with the younger generation than those grown in mines. Came up with the lab to foster diamond gave consumers a new choice. A more progressive young people when choosing diamond jewelry and wedding ring, will consider laboratory cultivation of diamonds.
