  • Chemical Composition: Labradorite is a feldspar mineral and belongs to the plagioclase series. Its chemical formula is (Ca,Na)(Al,Si)4O8, indicating a combination of calcium (Ca), sodium (Na), aluminum (Al), and silicon (Si) within its crystal structure.

    Crystal System: Labradorite crystallizes in the triclinic crystal system. This means that its crystals have three unequal axes and angles that are not right angles.

    Color: The most distinguishing feature of Labradorite is its remarkable play of colors, known as labradorescence. This optical phenomenon results from the interference of light between layers in the stone, producing vibrant flashes of blue, green, gold, and sometimes other hues.

    Hardness: On the Mohs scale of mineral hardness, Labradorite typically scores between 6 and 6.5. This moderate hardness makes it suitable for various jewelry applications.

    Luster: Labradorite exhibits a vitreous to pearly luster when polished, contributing to its captivating appearance.

    Transparency: Labradorite is generally translucent to opaque. The translucent varieties allow light to penetrate the stone, enhancing the visibility of its labradorescent play of colors.

    Occurrence: Labradorite is found in various locations worldwide, including Canada, Finland, Madagascar, Russia, and the United States. The most famous labradorite deposits are in Labrador, Canada, where the stone gets its name.

    Geological Formation: Labradorite is typically associated with igneous rocks, particularly basalt. It forms in the late stages of the cooling process of molten rock, often within cavities or along fractures.
