* What is Star Sapphire Synthetic Diffusion?
- We will try to be as non-technical as possible in answering this question. The diffusion process of star sapphires starts with picking a sapphire gemstone. The treatment is then done to bring the star effect on the surface of the sapphire gemstone. The main point to remember here is that, the star effect is only on the surface of the gemstone and does not extend to the entire gemstone. * Is the Diffusion can make to Lab Created or Synthetic Sapphire?
- As we explained that diffusion treatment can make on sapphire stone. Lab Created or Synthetic Sapphire gemstone with a hardness of 9 Mohs which the sapphire gemstone is extremely hard and measures 9 on the Moh\'s scale of hardness. The hardness of the gemstone is not affected by the diffusion process and the gemstone therefore retains it\'s originally physically properties. More reason which we make the star sapphire on Lab Created or Synthetic Sapphire Stone, because of limitation of Natural Sapphire, can make star sapphire diffusion only on Blue Star Sapphire and Black Star Sapphire, but in Synthetic Sapphire Stone can make to all colors. This is specially true of sapphires which are extremely hard and scratch resistant gemstones.
