Physical properties
Hardness: 2.0 (Mohs scale); Color: Tan, beige, or white with sand inclusions; Luster: Pearly to dull; Crystal structure: Monoclinic; Cleavage: Good in one direction but obscured by sand; Specific gravity: 2.3
Formation & geological history
Formed in arid, sandy environments through the evaporation of mineral-rich groundwater. The crystals grow in a radial habit, trapping sand grains inside the crystal structure to create the petal-like shapes.
Uses & applications
Primarily used as decorative specimens for mineral collectors, spiritual/metaphysical practices, and home decor.
Geological facts
The 'petals' are actually bladed crystals of either gypsum or barite. Because they are Mohs hardness 2, you can often scratch them with a fingernail.
Field identification & locations
Identified by its cluster of bladed crystals resembling a rose flower and its sandy texture. Found in deserts of Mexico, Tunisia, Libya, and the United States (Oklahoma/Arizona).
