White MoonStones Oval Cabochons, AA-Grade

This oval AA-grade white moonstone cabochon presents an ethereally transparent, watery milk-white color and the signature adularescence moonstone is known for. Consider setting this gemstone with a dark or black underlay, or in a highly oxidized setting; a dark background will effectively bring out its glow. Moonstone is a member of the feldspar-group mineral orthoclase and features an iridescent sheen called "adularescence." Some believe that, to be correctly called moonstone, the makeup of a given gemstone is less crucial than the presence of the characteristic adularescence. In true moonstone, however, this characteristic is due to the presence of albite inclusions within the gemstone and the reflection of light from the crystalline structure. Ancient Romans believed moonstone to be rays of moonlight transformed into a solid form.
