Labradorite

Labradorite properties at a glance

Geology & background

Forms in mafic igneous rocks. The iridescence comes from light diffracting through thin layers of different feldspar compositions.

Indigenous peoples of Labrador believed labradorite fell from the frozen fire of the Aurora Borealis.

How to identify Labradorite

• Check whether the specimen's color and texture match typical Labradorite examples.
• Photograph a fresh surface in natural light and avoid shadows, glare, or wet surfaces.
• Use hardness, streak, luster, grain size, and locality together; no single trait is enough for every specimen.

Where Labradorite is found

Labradorite is reported from multiple localities or geological settings. Exact locality should be verified from specimen provenance, maps, or field notes.

How much is Labradorite worth?

Value depends on size, condition, color, crystal quality, locality, rarity, preparation, and provenance. Treat this as educational guidance, not an appraisal.

Common uses

• Jewelry
• Decorative objects
• Building stone

Interesting facts

• Discovered in 1770 on Paul's Island, Labrador, Canada
• Inuit legends say it contains the Northern Lights
• Spectrolite from Finland shows the full spectrum of colors

Care & safety

Treat Labradorite as a collector specimen unless hardness, cleavage, and fracture are confirmed.

Avoid inhaling dust. Do not cut, grind, or polish unknown specimens without eye protection and a properly rated respirator.
