1.19 carat g VS1 IDEAL Cut Grade Round lab diamond

  When the technology for lab grown diamond first came out, the cost was not as high as that of natural diamonds, but it was not affordable for the general public either. So jewelers had no intention of using man-made diamonds to make diamond rings. And there were flaws in the manufacturing technology at the time, such as the fact that a small number of nitrogen atoms would still enter the experimental equipment throughout the manufacturing process, causing the man-made diamond to take on a slight yellow color. 

  Secondly, the physical structure of a natural diamond is ortho-octahedral, whereas a man-made diamond is not, resulting in a phosphorescent phenomenon. These cosmetic flaws were a fatal drawback for jewelers, but irrelevant for industrial equipment, so the earliest man-made diamonds were mainly used for industrial purposes.

  As society developed and people's living standards rose, they slowly reached a point where they could accept artificial diamonds. As a result, jewelers began to make diamond rings with synthetic diamonds. As a result of the technological advancement of man-made diamonds, the quality of man-made diamonds is now very high. From the naked eye alone, we can no longer tell whether a diamond is lab grown diamond or not.
