Moonstones form in the heat of the earth as orthoclase and albite are mixed together. As they cool, they separate into layers. The light that reflects off of these layers creates the moonstone's famous blue schiller. Moonstones have a storied history: the ancient Greeks called it Aphroselene for Aphrodite, the Romans believed that the goddess Diana could be seen within it, and Europeans of the Middle Ages believed that gazing into a moonstone would bring about prophetic dreams. At the turn of the 19th century, the Art Nouveau movement and its obsessions with the organic and ephemeral made gauzy gems like moonstone very popular in jewelry. This outstanding necklace is made in gold with a stunning fringe of moonstone cabochons combined with swags of chain.
