chinese wholesale jewelry What materials are made of artificial diamonds now?

wholesale baby jewelry hong kong Artificial diamonds are a multi -crystalline diamond that convergence of diamond crystals of 10 to 30 nanometers in diameter. Early artificial diamonds are light sugar and dilute colors due to the nitrogen atom in the air into the diamond crystals. There is no difference between the production of artificial diamonds and natural diamonds in appearance. Due to the different environmental environment, the molecular structure of the artificial diamond is not a complete octopus structure of natural diamonds but a complex structure, which will cause phosphorus light. With the maturity of artificial diamond production technology, its cost is low, and diamonds of various colors can be made to emerge in the jewelry market. Although there are decades of history from laboratory or factories, artificial diamonds with gem quality have only appeared recently. Artificial diamonds were originally used to make industrial uses such as cutting tools, but now they are also used on jewelry. The rule of fair transactions requires artificial diamond merchants to truthfully explain their quality and use their quality and use generally accepting words to describe, such as "artificial synthesis", "artificial" or "laboratory manufacturing". Almost all artificial diamonds belong to IB, and this type accounts for less than two % of natural diamonds. There is an unpleasant device that can verify IB diamonds, but to determine whether a diamond is artificially synthesized, it depends on the detection of a qualified gem laboratory. In 1954, artificial diamonds were successfully synthesized for the first time. At that time, a group of researchers from general electrical appliances created a diamond in the laboratory. They imitated the environment of diamonds in nature and gave carbon to extremely high temperature and high pressure. Also in the 1950s, another method of making synthetic diamonds was successfully developed. This method called chemical gas deposition (CVD), at a very low pressure and relatively low temperature, carbon carbon -containing carbon -containing with carbon content Mixed gas deposits into a diamond matrix.
