Selenite is one of a very few minerals with the specific metaphysical capabilities/properties that make it capable of clearing and re-charging other crystals. Not only is Selenite useful for clearing negative or unwanted energies from crystals and stones, it may also be used to effectively clear ritual and ceremonial tools, jewellery, tarot cards, even the surroundings. In addition to a multitude of other metaphysical attributes, Selenite has a calming and uplifting quality similar to Fluorite. Comprised of some of the lightest elements on earth (calcium, sodium, oxygen, and hydrogen), Selenite vibrates to a very high frequency, and for this reason, is an extremely powerful light working tool. In addition, it is a natural form of fiber optic, making it especially useful for transmitting white light, and coloured light. Selenite is a crystalline form of Gypsum. The beautiful Satin-Spar variety is bright white, opaque, and light refractive (light shimmers on its surface). The Gem-Ice variety is crystal clear, allowing it to absorb and emit light. Both forms are exceptionally energetic, and versatile, making Selenite an outstanding tool for use in crystal work Selenite does not ever need to be cleared. It is self-clearing, and self-charging. It is also important to note that Selenite should never be placed in or near liquid, as it is water-soluble, and will dissolve over time .
