Diamonds cultivated in the laboratory are real diamonds in all aspects, and all the characteristics such as chemistry, physics, atoms and optics are the same as mine drills. Cultivating diamond is a kind of diamond produced and cultivated by artificial method, which simulates the crystallization characteristics of mine drill. Cultivating diamonds in the laboratory has five advantages. (1) Innovative technology: The diamonds cultivated in the laboratory are diamonds produced in a high-tech instrument, which simulates the environment required for producing minerals in the natural environment. Diamonds cultivated in the laboratory 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 cultivating diamonds in the laboratory has not given up the pursuit of its quality and value on the premise of environmental protection. It adopts the same 4C grading standard as mineral diamonds, and also has an appraisal certificate issued by an international third-party diamond appraisal institution. ③ Green Earth: The cultivated diamonds are created by the best scientists, professional engineers and skilled technicians. They only use sustainable energy such as electricity and solar energy, and use greenhouse gas methane as the source of carbon atoms, instead of destructive mining by large machinery. 4 nouveau riche resources: Experts predict that the most important invention in this century will be to cultivate diamonds. Cultivating cheap diamonds will replace the role of silicon in semiconductors and let human science and technology enter another world. ⑤ Price advantage: Compared with mineral diamonds, diamonds cultivated in the laboratory are more loved by the younger generation. The emergence of diamonds cultivated in the laboratory has undoubtedly brought new choices to consumers, and more avant-garde young people will consider cultivating diamonds when choosing diamond ornaments and wedding rings.
