Drape yourself with some Mid-Century moonstone magic. This celestial set of dreamy moonstones and bright blue sapphires will add a little piece of the heavens to your neckline--and ears!​​​​​​​​ ​​​​​​​​ Moonstones present a phenomenon known as adularescence--a billowy moonlight-like sheen caused by the diffraction of light as it hits the thin mineral layers of the stone. It's no wonder that the Romans, who, from about 100 A.D. used moonstones in jewelry, thought that the lustrous gems were formed from the light of the moon.​​​​​​​​ ​​​​​​​​ Until the 1800s, moonstones were believed to make people invisible, permitting only their spirits to wander. ​​​​​​​​ ​​​​​​​​ Disappearing acts aside, moonstone was a favored gem by Art Nouveau designers including Louis Comfort Tiffany and it continues to be a most alluring and desired gem.
