- Selenite Citadels
Selenite is another form of gypsum that has a uniform structure and more clarity than gypsum. Chemically speaking, this monoclinic stone is hydrous calcium (calcium is found in mica of mineral makeup) sulphate. The formation of Selenite is a result of evaporation in clay beds near hot springs. Absolutely beautiful specimen!
