3ct 4ct HPHT Lab Grown Diamonds DEF Color VVS VS Clarity For Jewelry
Lab Created Diamonds Description
Lab created diamond in 1952, by the United States federal Silicon Carbide company scientist William Everso using chemical vapor deposition method for the first time discovered lab created diamonds, and in 1954 after general Electric "super pressure project" director Dr. Hall led a team, in the field of artificial lab created diamonds made further development, It has made great contributions to lab created diamonds for the later generations, and the birth of the first "high temperature and high pressure method to lab created diamonds", and in 1970, the United States General Electric successfully cultivated the first big diamond of gem level through improved technology.
After years of development, the technology of lab created diamond is becoming more and more sophisticated, so artificially lab created diamonds are gradually coming to the market. Moreover, in normal life, lab created diamonds and naturally formed diamonds are almost the same in appearance, color and size. If you do not take some professional instruments for analysis and detection, the naked eye can not be identified. Even some people in the diamond color and quality is far, higher than the natural diamond.
For growing diamonds, distinguishing natural diamonds can only be detected in special ways, such as under the irradiation of a cathode light meter. Lab created diamonds have a geometric growth pattern while natural diamonds have a ring pattern. And since 2006, thanks to the popularity of artificial diamond technology. GIA and other jewelry institutions also began to issue certificates for lab created diamonds, the main purpose of which is to prevent some illegal merchants in the society from taking advantage of lab created diamonds as natural diamonds to make profits by selling substandard diamonds as advanced ones, thus damaging the market.
