Formation & geological history

Formed in arid, sandy desert environments through the evaporation of shallow, salty water basins. Intersecting bladed crystals trap sand grains within their structure as they grow.

Uses & applications

Popular as a decorative display mineral and collector specimen; widely used in metaphysical collections and crystal healing practice.

Geological facts

Also known as Sand Rose, Rose Rock, or Selenite Rose. Native Americans in Oklahoma used rose rocks as currency, and Oklahoma made the barite variant its official state rock.

Field identification & locations

Identified by its distinctive rosette-like pattern composed of flattened bladed crystals impregnated with sand. Common in dry lake beds and desert regions like Morocco, Tunisia, Mexico, and Arizona.
