This gem derives its name from the unique play of light from its surface. This is termed phenomena adularescence and it arises from internal, lamellar form of the crytalline structure.
Moonstones are very soft stones, and benefit most from a Cabochon cut. They are birthstone for June, as well as the gem given out at a 13th wedding anniversary. Moonstones are very affordable, but blue moonstone supplies are dwindling and this variety is becoming more expensive.
