Physical properties

Formation & geological history

Formed in arid, sandy environments through the evaporation of salt-rich water cycles. The crystals grow in the spaces between sand grains, trapping the sand within the crystal structure as they expand.

Uses & applications

Primarily used for mineral collecting, decorative display, and metaphysical practices. Gypsum is used in plaster and drywall, though desert rose specifically is a specimen variety.

Geological facts

The 'petals' are actually flattened crystals that follow the mineral's cleavage planes. They are most commonly found in the Sahara Desert and it is considered a symbol of the 'inner truth' in some cultures.

Field identification & locations

Identify by its unique rose-like blade configuration and sandy texture. Commonly found in desert regions of Algeria, Tunisia, Morocco, Mexico, and the USA (Oklahoma). To test, gypsum can be scratched with a fingernail.
