Physical properties

Hardness: 2 on Mohs scale; Color: white, tan, or sandy; Luster: vitreous to pearly; Crystal structure: monoclinic; Cleavage: perfect in one direction; Specific gravity: 2.3

Formation & geological history

Forms in arid environments through the evaporation of salt-rich water over centuries, creating bladed crystal clusters that trap sand grains.

Uses & applications

Primarily used as decorative display specimens, in lapidary work, and by mineral collectors.

Geological facts

The 'petals' are actually flattened crystals that radiate out from a central point. They are common in the Sahara Desert and parts of the United Arab Emirates.

Field identification & locations

Identify by its unique rose-like bladed structure and low hardness (can often be scratched by a fingernail). Found in dry, sandy basin areas.
