Labradorite is a calcium sodium compound coming from the feldspar family of spectacular stones. The crystal make-up of this interesting gemstone allows an otherwise opaque mineral to exhibit an unusual glowing effect. This is due to the large crystal masses that allow a play of iridescent color over the surface similar to opal and abalone. Stunning even in rough, Labradorite slabs or sheets offer bright, stained-glass luster straight from the mine.
Often cobalt, royal or silvery blue to iridescent purples and moss to olive green with streaky black, white or silver, Labradorite also comes in paler tones. Mirrored-gray, peachy beige, and barely tinted gunmetal silver colors are more likely to be translucent than the darker shades. These are usually flecked with tiny black spots. These colors are further defined by the names sunstone and spectrolite. The spectrolite form of Labradorite is the deeper cobalt to midnight blue stone liberally streaked with plays of bright orange-gold streaks, while sunstone is lighter in color and has more translucence.
Labradorite blues and greens offer a shimmering spectrum of light to pass across the gemstone’s surface due to what is known as the schiller effect, meaning light refracts within the stone’s lamellar intergrowths. Nearly transparent Labradorite is valued as a gemstone, often appearing similar to topaz, and is sometimes faceted. The prismatic qualities of blue, reds, and golds of this stone make for fiery cabochons, usually cut into round, oval, and teardrop or triangle shapes. The brilliance and fickle play of light in Labradorite also make it a choice for avante garde and nouveau designs, often paired with shell, abalone, mother-of-pearl, and lapis or silver. Labradorite is most often set into rings, earrings, cufflinks, beads, and pendants, sometimes in free-form shapes.
