Mystic topaz is a fairly new gemstone, created by coating a clear topaz with a very thin chemical layer, which enhances the stone and makes it appear rainbow-colored. The iridescence is so beautiful, with fiery colors of the rainbow. This particular ring is a round cut mystic topaz center stone in a hexagon-shaped solid Sterling Silver (hallmarked) setting. Framed by round cut AAA cubic zirconia, the crystal clear stones give the perfect contrast to this radiant solitaire stone. gold_dust4217
