This is a beautful piece of polished Labradorite from Madagascar.
It is 649 grams, and measures 116 x 77 x 39 mm.
I actually bought this one some time ago because of the face appearing from the blue light, and I find this piece more interesssting than the common ones on the market.
The name "Labradorite" comes from Labrador county in Canada, where this mineral first was found.
Some Ancient Inuits believed that Labradorite was the frozen fire of the Aurora Borealis. Legend says that an Inuit warrior found a cave with the Aurora Borealis embedded within the rocks, on the shoreline of Labrador, Canada. He attempted to release the Aurora Borealis with his spear but was unable to remove it all, leaving some of the light imprisoned in the rocks forever. The native inhabitants used the gemstone for medicinal purposes as they believed that it would increase their energy as well as reducing stress and anxiety.
