Physical properties

Hardness: 6-6.5, Color: Blackish-gray with iridescent flashes, Luster: Vitreous to pearly, Crystal structure: Triclinic, Specific Gravity: 2.68-2.72.

Formation & geological history

Formed in igneous or metamorphic rocks when plagioclase feldspar crystallizes from cooling magma or under heat and pressure. Most high-quality specimens date from the Proterozoic era.

Uses & applications

Primarily used for jewelry, gemstone carvings (as seen in the animal figure), ornamental stones, and spiritual/metaphysical collecting.

Geological facts

The iridescent color effect is known as labradorescence, caused by internal light reflections within microscopic layers of the mineral. It was first officially discovered in Labrador, Canada.

Field identification & locations

Identify by rotating under a light source to find 'schiller' or iridescent flashes of blue, gold, or green. Commonly found in Canada, Madagascar, and Finland (Spectrolite).
