A lovely labradorite focal bead I custom cut with material from Madagascar. Measurements are in the title in millimeters and it has a 2.5mm drill hole. CHAIN NOT INCLUDED. Feel free to check out all the items in my DVHdesigns Handmade Storefront and once there you can contact me with general inquiries or about a custom order. Thanks for shopping DVHdesigns!
NOTE: Some people call this "spectrolite", which is incorrect. Spectrolite is a trade name for high quality labradorite from Finland and only Finnish labradorite may accurately be called spectrolite! Nearly ALL the commercial labradorite one sees is from Madagascar. Very, very little comes from from Labrador or Finland! I have worked with all three and buy the rarer material directly from people from those countries.
Here's the geological info on labradorite from Wikipedia, 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. 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.
Here is some metaphysical information about labradorite that I found online, "Labradorite is said to provide quick relief from anxiety, hopelessness and depression, replacing them with enthusiasm, self-confidence and inspiration. It is said to dispel negativity and to bring clear understanding by enhancing clarity of thought and improving one's ability to cooperate with others in harmony. Labradorite is also said to give perseverance, strength and enhanced intuition when one is experiencing times of conflict and change. Labradorite is told to be helpful in treating eye and brain disorders, and to help regulate metabolism and the digestive process. A sister to moonstone, labradorite links to the "darker" Crone aspects of the Goddess, and grants inner knowing of Mystery. It enhances intuition and psychic perception; just like the cord-cutting Crone, it helps the bearer to release judgment, and understand their destiny. Use it to bring Light to the shadowed realms of the self and to connect with the power of the waning Moon. "
