Labradorite is plagioclase feldspar. A grey stone can suddenly flash electric blue or green when the viewing angle lines up with its internal structure. This page separates mineral facts from retail terminology and traditional crystal symbolism so you can compare pieces more confidently.

What Labradorite is

Labradorite forms in igneous rocks; microscopic intergrowth structures create labradorescence, the coloured flash seen at certain angles. Its listed Mohs hardness is 6–6.5, and its crystal system or structural category is Triclinic. The chemical composition is commonly written as (Ca,Na)(Al,Si)₄O₈.

What to look for when buying

The flash should move or disappear as the angle changes. Static painted colour on the surface is not labradorescence. Treatments are not automatically a problem, but they should be disclosed. For labradorite, common treatment or enhancement notes include: Usually untreated, though oiling, resin filling and coatings may appear in decorative material.

Care and display

Water: Brief contact with water is usually fine, but avoid soaking fractured pieces. Light: Ordinary indoor light is fine; protect polished surfaces from abrasion.

Traditional associations

In modern crystal traditions, labradorite is often associated with transformation, intuition, protection. These are cultural or spiritual associations rather than scientifically demonstrated effects. A crystal should not be used as a substitute for medical, mental-health, financial or other professional advice.

Where it works visually

Common display ideas include desk, living room. Placement should also account for hardness, cleavage, sunlight, humidity, pets, children and how easy the specimen is to knock over.

Common sources

Material sold under this name is commonly sourced from or associated with Madagascar, Canada, Finland, Worldwide. A country name on a listing is not the same as mine-level provenance; individual specimens should keep their own supplier and locality records whenever possible.
