Lab Grown Diamonds Description
Cultured diamond refers to synthetic diamond, which is a kind of polycrystalline diamond made from the aggregation of diamond crystals 10 to 30 nanometers in diameter. The molecular structure of artificial diamond is not the complete octahedral structure of natural diamond, but a complex structure, which will produce phosphorescence phenomenon. With the maturity of artificial diamond production technology, its low cost, and can produce a variety of colors of diamonds and in the jewelry market.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Lab-grown diamonds are true diamonds in every respect, having the same chemical, physical, atomic, optical and all properties as mine diamonds; Cultured diamond is generated and cultivated by artificial method to simulate the crystallization characteristics of ore drill. There are five advantages to lab-grown diamonds. ① Innovative technology: the laboratory cultivation of diamonds is in a high-tech instrument, simulation of the natural environment of the mine drilling to generate the required environment and the generation of diamonds. Lab-grown diamonds are created by the best scientists, professional engineers and skilled technicians, and are the crystallization of human scientific and technological wisdom. ② Excellent quality: the concept of laboratory cultivation of diamond in the premise of environmental protection, did not give up the pursuit of its quality and value. It adopts the same 4C grading standard as mineral diamonds, and also has an appraisal certificate issued by an international third-party diamond appraisal agency. ③ Green Earth: Cultivating diamonds is created by the best scientists, professional engineers and skilled technicians, using only sustainable energy such as electricity and solar power, and using the greenhouse gas methane as a source of carbon atoms, rather than destructive mining by large machinery. Experts predict that the most important invention of this century will be the lab grown diamonds. Cheap, lab grown diamonds could replace silicon as a semiconductor, bringing human technology into another world. ⑤ Price advantage: laboratory-cultivated diamonds are more loved by the younger generation than mine diamonds. The emergence of laboratory-cultivated diamonds undoubtedly brings new choices to consumers. More avant-garde young people will consider lab grown diamonds when choosing diamond ornaments and wedding rings.
