2.2" Ram's Horn Selenite Formation - Morocco

This is a natural gypsum var. selenite (ram's horn) formation that was collected from the Bou Azer East Deposit of Morocco. The selenite formed by expanding from the matrix beneath, however this specimen features selenite that has been removed from the matrix.

Selenite is a variety of gypsum, a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4 · H2O). When chemically pure, gypsum is transparent and colorless, but impurities give the gypsum a diverse range of colors and formations. Desert rose selenite and satin spar are just a few of the varieties of gypsum known to have formed though hydrothermal processes.
