What it is?
Desert rose is the given name to gypsum crystals which contain abundant included sand grains and crystallises under a “rosette” shape. The “petals” are crystals flattened on the c crystallographic axis, fanning open in radiating flattened clusters. These are formed in arid sandy conditions such as the evaporation of a shallow salt basin. The desert rose may also be known by the names: sand rock, rose rock, selenite rose, gypsum and barite rose.
For connoisseurs, this is also a famous french dessert, named “Rose des sables” made of corn flakes and chocolate, “un délice!!!”
