Selenite, also known as Satin Spar and Desert Rose is a clear variety of gypsum, selenite crystals often form as seawater evaporates. As they become heavier, these crystals sink to the bottom of the sea bed. Strangely enough Selenite can be permanently damage if exposed to water, so do not cleanse or immerse it in water for any reason.
Although the name Selenite means ‘moonstone’ it has no connection with the other more beautiful and durable Moonstone gemstones. The silvery quality of the stone may have reminded those who name it of the moon, and in turn the Greek moon goddess Selene.
