Selenite crystal is one of the 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.

In addition, it is a natural form of fibre optic, making it especially useful for transmitting white light, and coloured light. Selenite is a crystalline form of Gypsum. The Gem-Ice variety is crystal clear, allowing it to absorb and emit light.

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.
