LABRADORITE – a plagioclase mineral with a composition of 50-70, an intermediate member of the albite-anorthite solid solution series. It is closer in composition to anorthite, making it a variety of the mineral anorthite.

Special properties:
Labradorite often displays iridescence (an optical effect visible in bright light as an internal rainbow-like glow). The iridescence may vary in its distribution, ranging from wavy to mosaic-like, and in color, from monochromatic to multicolored, covering the entire rainbow spectrum. In Western gemology, this phenomenon is called labradorescence. It results from interference at the boundaries of thin twinning lamellae of varying composition, encompassing the full spectrum from red to violet.
Diagnostic features
Labradorite exhibits parallel striations due to polysynthetic twinning, visible on cleavage planes.
Its similarity to beryl arises from matching density and refractive indices.
When iridescent labradorite with pale color is heated to 500–700°C for 3–5 hours, its coloration intensifies, revealing bright pink, yellow, and brown tones. This is a method of enhancing labradorite stones.
Additionally, highly fractured translucent labradorite specimens are enhanced with fillers containing blue dye. This treated material is often sourced from India and available as faceted stones or cabochons.
In the 21st century, a technique was developed to create rainbow labradorite with polychromatic iridescence by applying a thin film of precious metal to cabochons or faceted stones.
Morphology
Labradorite forms massive granular aggregates, large crystalline masses, and less frequently, individual crystals with tabular and tabular-prismatic shapes. Complex polysynthetic twinning and zoning are commonly observed in labradorite crystals.
Origin
Labradorite can be found in igneous (both plutonic and volcanic), metamorphic, and sedimentary settings.
Uses
Labradorite is used as a decorative and ornamental stone.
Transparent labradorite crystals are faceted into gems, sometimes weighing up to 20 carats, with some of the largest gems historically reaching 100 carats. As a faceted gem, labradorite became widely recognized in the U.S. due to discoveries of transparent crystals in the country.
Translucent labradorite with optical effects is typically shaped into cabochons.
Healing properties
It is believed that labradorite can help with infertility, joint issues, prostate problems, and certain urinary system diseases. Some believe that labradorite alleviates spinal pain and enhances metabolism, aiding in the removal of kidney stones.
Magical properties
Labradorite is thought to strengthen visionary abilities and revelations, developing endurance in its owner.
It is also believed to stabilize a person’s aura and serve as a talisman that protects the home from uninvited guests.

Interesting Facts
In Kievan Rus, labradorite, known as "peacock stone," was recognized as early as the late 10th century and was used to adorn churches.
In jewelry, labradorite found its use after its first shipment to Western Europe in 1775.
In the 19th century, labradorite items adorned with diamonds were fashionable in London and Paris.
