DESERT ROSE

CaSO4·2H2O (gypsum) or BaSO4
(barite) — rosette-shaped crystalline aggregate
More information
Typically sourced from the Sahara Desert (Morocco,
Tunisia, Algeria), North America, and Australia, this forms by
evaporation of saline waters in arid desert settings; sand grains
incorporated during growth give the typical ochre color . Hardness 2–
3.5 Mohs (gypsum softer , barite harder).
A very popular ornamental and collector
object for its naturally flower-like form; used in interior décor;
educationally valued to illustrate evaporation and evaporite processes.
