Desert Rose — Rose-like formation of crystal clusters

Desert rose is the colloquial name given to rose-like formations of crystal clusters of gypsum or baryte which include sand grains. The ‘petals’ are crystals fanning open in radiating flattened crystal clusters. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions, such as the evaporation of a shallow salt basin. The crystals form a circular array of flat plates, giving the rock a shape similar to a rose blossom.
