PACK OF 10 - Tiny Selenite Pocket Hearts / 30-40 mm avg. 100% Natural Moroccan Selenite Measures at approximately 30-40 mm "Selenite" is the crystallized form of the soft mineral Gypsum. In antiquity, it was believed selenite waxed and waned with the cycles of the Moon inspiring it's name which stems from the Latin word selenites, meaning "moon stone". It is often silky and waxy to the touch and contains natural veining and translucency, allowing light to illuminate it's unique features. Selenite is soft, being only a 2 on the Mohs scale, and water soluble so it is important to handle it delicately and keep it away from liquid. This listing is for ten (10) pieces.
