Desert Rose Selenite, also known as Gypsum Rose or Sand Rose, is a type of Selenite formed from a combination of water, wind, and sand. Sand becomes embedded in Selenite blades, while additions of water overtime help form the signature “rosette” formation. Most specimens on the market have been brushed lightly with a torch to help define these rose petal shapes, though it does not affect the energy of these stones. Minor nature cracks & chips. 18-9.5-7.5 inch.
