Labradorite has a silky appearance and is a dark grey to gray-green stone with flashes of blue, green and occasionally red. Labradorite can be transparent (rare) and can appear as colorless or as brown-red, green, brown-green, or even red, but the dark green-grey color is typically seen in jewelry. As you might guess, Labradorite is named for Labrador, Newfoundland in Canada. It is found there, but can also be found in Mexico, the USA, Finland, Madagascar, and Russia.
Labradorite shows what is termed a Schiller (also called Labradorescence) – flashes of blue, red, and green due to the internal structure of the stone. These color flashes make Labradorite a popular stone for jewelry. It is often seen cut as cabochons with a smooth polished curved surface, but they can also be faceted – particularly the unusual transparent varieties. Labradorite varieties that exhibit a high degree of labradorescence are called spectrolite
Perfection in appearance is of primary importance in a finished gemstone. Many gemstones have long and complex histories. Some gems have a lot of historical lore attached to them as well as perceived powers , healing effects, and protections.
