Physical properties

Formation & geological history

If labradorite, it formed as plagioclase in cooling igneous rock; its geological age depends on its source. The rounded shape appears to result from tumbling or natural abrasion.

Uses & applications

Tumbled stones are used in jewelry, crafts, and collections; value depends on confirmed material and optical quality.

Geological facts

Labradorite can display vivid blue, green, or gold iridescence (“labradorescence”), which is not clearly visible here.

Field identification & locations

Identification would require checking for labradorescence and testing physical properties; many common stones can look similar when tumbled. Labradorite occurs in igneous rocks, notably in Labrador, Canada, and Madagascar.
