Physical properties

Formation & geological history

Formed in arid sandy conditions through the evaporation of shallow salt basins or groundwater. These crystals grow as a cluster of flat blades, incorporating sand grains into their structure. Most are from the Quaternary period.

Uses & applications

Primarily used as decorative display specimens, in mineral collections, and occasionally in holistic practices or as metaphysical stones. Not typically used in construction due to fragility.

Geological facts

The 'pedals' are actually crystals of gypsum or barite that have incorporated sand grains during growth. The Oklahoma Rose Rock was the first rock to be named a state rock in the USA (1968).

Field identification & locations

Identify by the unique circular, bladed 'rose' shape and sandy texture. They are extremely soft (gypsum variety can be scratched with a fingernail). Commonly found in the Sahara Desert, Mexico, and Oklahoma.
