Physical properties

Hardness: 2 (Gypsum) or 3-3.5 (Baryte); Color: Sand-like, tan, or white; Luster: Pearly to dull; Crystal structure: Monoclinic or Orthorhombic bladed clusters; Cleavage: Perfect; SG: 2.3 - 4.5

Formation & geological history

Formed in arid, sandy environments through the evaporation of mineral-rich water in shallow salt basins or within sand dunes during dry cycles.

Uses & applications

Primarily used for decorative purposes, mineral collecting, and metaphysical uses; sometimes used as a source for gypsum products in construction.

Geological facts

The 'petals' are actually bladed crystals of Gypsum or Baryte that trap sand grains as they grow, creating a flower-like rosette shape. They are iconic symbols of desert geology.

Field identification & locations

To identify in the field, look for rose-shaped clusters in desert basins or dry lake beds. They are very fragile and soft, often found just below the surface of the sand.
