Physical properties

Formation & geological history

Formed in arid, sandy environments through the evaporation of salt-rich groundwater in shallow basins. The crystals trap sand grains within their structure as they grow into a rosette shape.

Uses & applications

Primarily used as decorative display specimens, in mineral collections, and in metaphysical/spirituality practices. Gypsum in other forms is used in drywall and plaster.

Geological facts

Despite their delicate appearance, these are inorganic crystal clusters. The largest Desert Rose ever recorded was found in Algeria and measured over 40 centimeters in length.

Field identification & locations

Identify in the field by the characteristic petal-like bladed crystals and sandy texture. They are extremely soft and can be scratched by a fingernail. Common in the Sahara Desert, Saudi Arabia, and the Southwest United States.
