Physical properties

Hardness: 2 (Mohs scale); Color: Tan, sandy, or peach; Luster: Pearly to dull/earthy; Crystal structure: Monoclinic, forming bladed clusters; Cleavage: Good; Specific gravity: 2.3

Formation & geological history

Formed in arid sandy conditions through the evaporation of shallow salt basins or groundwater. Crystals grow into a circular rose-like pattern, trapping sand particles within the crystal structure as they form.

Uses & applications

Primarily used for decorative purposes, crystal healing collections, and as educational geological specimens. Gypsum itself is used in plaster and drywall.

Geological facts

The 'petals' are actually flattened crystals that follow the rose-like symmetry. They can contain up to 50% sand by weight. Some clusters can grow to hundreds of pounds, though most are small palm-sized pieces.

Field identification & locations

Identified by its distinctive rose-like bladed clusters and sandy texture. Commonly found in North Africa (Sahara), the Middle East (Qatar, UAE), and the United States (Oklahoma, Arizona). It is very soft and can be scratched by a fingernail.
