AI-generated identification · may be incorrect

Polished gray-green stone with muted golden patches; feldspar hardness 6–6.5 Mohs, vitreous luster, triclinic crystals, and two cleavages near 90°. The subdued color play is consistent with labradorite, though the photo cannot confirm the identification.

Physical properties

Formation & geological history

Forms as plagioclase crystals in cooling mafic igneous rocks, especially gabbro and basalt; known deposits occur in Canada, Madagascar, Finland, and elsewhere. Its age depends on the host rock.

Uses & applications

Used for jewelry, carvings, and decorative stone; the pictured piece is fashioned as a pendant.

Geological facts

Labradorescence—bright, shifting blue, green, or gold flashes—comes from light interference in fine internal layers; this specimen shows limited visible flash.

Field identification & locations

Check for broad internal color flashes by tilting the polished stone; feldspar cleavage and hardness help distinguish it from glass. Similar-looking stones can be confused with other feldspars.
