Physical properties
Hardness: 2.0 (Gypsum) or 3.0-3.5 (Barite); Color: Tan, sandy, or brownish-white; Luster: Pearly to earthy; Crystal Structure: Monoclinic; Cleavage: Good in one direction; Specific Gravity: 2.3
Formation & geological history
Formed in arid sandy conditions when saline water evaporates, allowing crystals to trap sand grains as they grow into flat, bladed plates that resemble flower petals. Typically found in Quaternary deposits.
Uses & applications
Primary used as a decorative collector specimen, in meditation practices, or as a unique gemstone for carved and wired jewelry.
Geological facts
Despite their fragile appearance, these 'roses' are forged in some of the harshest desert environments on Earth. They are unique because the crystal habit is forced into a rosette shape by the immense pressure of the surrounding sand.
Field identification & locations
Identify in the field by its distinct flower-like petal arrangement of bladed crystals embedded with sand. Commonly found in the Sahara Desert, Mexico, and arid regions of the SW United States.
