While looking at a Sapphire ring (about 2 ct) over the weekend I noticed that instead of a deep dark stone there was what looked like an irridescent layer to the stone. The sales person mentioned that it was a natural untreated stone of a "prized" shade of blue but I had never seen the irridescent affect before and I was curious about what it was. Does anyone know? I noticed it when I looked at the stone from an angle. At first I thought the table might just be smudged but it was still there after the saleswoman steamed it.
