Selenite

What is Selenite?

Selenite was named after Selene the Greek goddess of the Moon, meaning literally the stone of the Moon (not to be confused with moonstone). The name alludes to the moon-like pale reflection the stone can give. Transparent to translucent with a glowing transparency, throughout history it has been compared to liquid light.

Occurrence

Although transparent and colourless, selenite can be lightly coloured due to inclusions or impurities, which manifest as pale pastel tints. crystals form in sedimentary rocks, specifically limestone, and they can grow to gigantic sizes in the right conditions.

 

The Cave of Crystals discovered in 2000 in the Naica mine in Chihuahua, Mexico, contains crystals of selenite as large as 1.2m in diameter and 15m in length - the world’s largest known crystals.
