Labradorite ((Ca,Na)(Al,Si)4O8), a feldspar mineral, is an intermediate to calcic member of the plagioclase series. It is usually defined as having "%An" (anorthite) between 50 and 70. The specific gravity ranges from 2.71 to 2.74. The streak is white, like most silicates. The refractive index ranges from 1.555 to 1.575. Twinning is common. As with all plagioclase members the crystal system is triclinic and three directions of cleavage are present two of which form nearly right angle prisms. It occurs as clear, white to gray, blocky to lath shaped grains in common mafic igneous rocks such as basalt and gabbro, as well as in anorthosites.
The geological type area for labradorite is Paul's Island near the town of Nain in Labrador, Canada. It has also been reported in Norway and various other locations worldwide.
It occurs in large crystal masses in anorthosite and shows a play of colors called labradorescence. The labradorescence, or schiller effect, is the result of light refracting within lamellar intergrowths resulting from phase exsolution on cooling in the Boggild miscibility gap, An48-An58.
Gemstone varieties of labradorite exhibiting a high degree of labradorescence are called spectrolite; moonstone and sunstone are also commonly used terms, and high-quality samples with good qualities are desired for jewelry.
Physical properties of Labradorite:
Color: Gray, Green Gray, Black with colorful shillers most often in golds, greens, blues and violets
Location: Brazil, Canada, China, Czech Republic, Germany, Madagascar, Norway, Russia, UK, Ukraine, USA
Fun Fact: Finnish Labradorite exhibits uniquely vivid colors of bright aqua, golden yellow, peacock blue, reddish orange, greens and red and is called Spectrolite. The Finnish "Stone of Light" was given the name Spectrolite by Professor Aarne Laitakari, who through the name, wanted to convey the colours of the Finnish Nature of various seasons.

Highly mystical, Labradorite heightens intuition and enhances psychic abilities, making it great for working with the Third Eye Chakra. Intuition and intellect are balanced by Labradorite, illusions are dispelled and true intentions are seen more easily with its use. Labradorite is also very protective against negative energies, balancing, strengthening and protecting the aura and sealing the aura from energy leaks.
Labradorite is a stone of transformation and change. Labradorite enhances strength of will and feelings of inner worth. It is useful for bringing up and healing old memories, including past life issues. Labradorite can also help prepare the body and soul for ascension.
Labradorite can aid in communicating with our highest self and with the creator. It helps to assists when facing and navigating all types of changes and challenges, attracting strength and perseverance. Labradorite is one of the best stones to use when dealing with any type of addiction or to break unhealthy (physical, mental, etc) habits.
