Desert Rose (Baryte or Gypsum Rose)
Baryte (BaSO4) or Gypsum (CaSO4·2H2O)
Rock Type: mineral

Physical Properties
Hardness: 2 (Gypsum) to 3.5 (Baryte); Color: Tan, sandy brown, or cream; Luster: Pearly to dull/earthy; Crystal structure: Orthorhombic or Monoclinic bladed clusters; Cleavage: Perfect; Specific gravity: 2.3 (Gypsum) to 4.5 (Baryte).
Formation & Geological History
Formed in arid, sandy environments through the evaporation of mineral-rich groundwater. As the water evaporates, it leaves behind crystals that incorporate sand grains, resulting in a rosette shape. These typically form in quaternary deposits.
Uses & Applications
Primarily used as decorative specimens for collectors, metaphysical purposes, and education. Gypsum variants are used industrially in drywall and plaster, while Baryte is used in drilling fluids.
Geological Facts
The 'petals' of the desert rose are actually crystals that have captured thousands of sand grains during their growth. Depending on the mineral content, they can be made of gypsum (lighter) or baryte (much heavier).
Field Identification & Locations
Identified by its distinctive rose-like cluster of flattened blades and sandy texture. Commonly found in the Sahara Desert, Saudi Arabia, and Oklahoma (where it is the official state rock).
