Desert Rose

It is the name given to rosette formations of the minerals gypsum and barite with sand inclusions. The 'petals' are crystals flattened, fanning open along characteristic gypsum cleavage planes. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions, such as the evaporation of a shallow salt basin.Desert roses are mineral formations that are found on the surface and are awesome examples of the natural power of the shaping forces of wind, water and pressure in dry, arid regions.Desert roses are only found in deserts, which is how they got the name.
