Diffusion rates for chromium are very slow; thus only a surface layer of color is found. The same process can diffuse titanium into the stone, producing an artificial asterism. Fracture filling: Oil, wax or plastic (with or without dye) Lead glass filling: Hides fissures, improves color and increases weight
Some stones might look like real sapphires, but they are actually fakes made of things like glass, cubic zirconia, or synthetic corundum. To spot these fake sapphires, you have to know how they look. They can be perfect, too bright, or lack the deep, mesmerizing blue of real sapphires.
