Physical properties

Hardness: 6-6.5 on Mohs scale. Color: Pale blue-green to teal. Luster: Vitreous to pearly. Crystal System: Triclinic. Cleavage: Perfect in two directions.

Formation & geological history

Forms in igneous rocks, predominantly granite pegmatites and syenites, through hydrothermal activity involving potassium-rich fluids.

Uses & applications

Used primarily as a gemstone, for lapidary work, beads, ornamental carvings, and in mineral specimen collections.

Geological facts

Its distinctive green-blue color was long believed to come from copper, but modern research indicates it is caused by trace amounts of lead and water trapped within the feldspar lattice.

Field identification & locations

Identified by its distinctive light blue-green hue, blocky cleavage, and hardness. Common localities include Colorado and Virginia (USA), Madagascar, Brazil, and Russia.
