Physical properties

Hardness: 6.5-7.0 (Mohs); Color: Pale pink to violet; Luster: Vitreous to pearly; Crystal structure: Monoclinic; Cleavage: Perfect in two directions; Specific Gravity: 3.16-3.20

Formation & geological history

Formed in lithium-rich granite pegmatites. These crystals are typically found in host rock environments associated with quartz, feldspar, and tourmaline, particularly in late-stage crystallization zones.

Uses & applications

Used primarily as a gemstone in jewelry (rings, pendants, and earrings) and highly valued as a specimen by mineral collectors.

Geological facts

Kunzite was first discovered in 1902 and named after George Frederick Kunz, the chief gemologist at Tiffany & Co. It is known for its intense pleochroism, meaning it can show different colors when viewed from different angles.

Field identification & locations

Identify in the field by its distinct pink color, flattened prismatic crystal habit with vertical striations, and perfect cleavage. Common locations include Afghanistan, Brazil, Madagascar, and San Diego County, California.
