Polished labradorite pendant

Labradorite, a calcium-rich plagioclase feldspar (approximately NaAlSi₃O₈–CaAl₂Si₂O₈)

AI-generated identification · may be incorrect

Dark gray to black, glassy luster, Mohs hardness 6–6.5, triclinic crystal structure, and good cleavage; the blue-green, gold, and violet flashes are labradorescence caused by light interference in thin feldspar lamellae.

Physical properties

Formation & geological history

Forms mainly in mafic igneous rocks such as basalt, gabbro, and anorthosite as magma cools; notable deposits occur in Canada, Madagascar, Finland, Norway, and Russia, generally from Precambrian to younger igneous settings.

Uses & applications

Commonly cut and polished for cabochons, pendants, beads, carvings, and decorative objects; it is valued more for strong, colorful labradorescence than for transparency.

Geological facts

The pictured object appears to be a small polished cabochon set in a metal pendant, so cleavage and crystal form are obscured. Stronger flashes usually appear when the stone is tilted relative to the light.

Field identification & locations

Identify it by its dark body color, prominent multicolor flash, moderate hardness, and feldspar-like cleavage; it should not show uniform glitter like man-made glass. Common commercial specimens come from Madagascar and Canada.
