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.
