Certificate 0.575ct FIY VS2 3EX Round lab diamonds video

  Under a microscope or 10x magnification, natural diamonds can see a variety of natural inclusions, laboratory diamonds do tend to see black metal inclusions, small particles can also be magnetized up, which is the most obvious feature of both.When viewed under fluorescent light, most natural diamonds fluoresce blue-white and synthetic diamonds fluoresce blue-green or orange-red. Friends who understand diamonds know that natural diamonds, except blue diamonds are semiconductors, other natural diamonds are not conductive, and no magnetic. But as long as the synthetic diamonds have thermal conductivity and electrical conductivity.
