My new stones to play with ,Labradorite, also called spectrolite or labrodite

Labradorite, also called spectrolite or labrodite, among many other names, is a type of feldspar that was officially found by Moravian missionaries in Labrador in Canada in 1770.

The Eskimo Inuit and the Native American Innu, natives of Labrador, have used labradorite for centuries. There are stories involving the discovery of labradorite, one of which tells of some "mighty being" coming upon the rocks where the stars once resided, and pounded on them to enable some of them to travel up to the sky, while a few remained. The native inhabitants of Labrador called the mineral "fire rock" or "firestone."

 

This was from a Canada mine source not much else was on the old box

 

labradorite variety that shows more that two spectral colors with brilliant spectral hues or iridescence, is called is called Spectrolite .

 

A labradorite is a combination of 30 to 50% of albite and 50 to 70% of anorthite. Albite is sodium aluminum silicate (NaCa AlSi3O8) and anorthite is calcium aluminium silicate (CaAl2Si2O8). The specific gravity is usually between 2.58 and 2.70 and the refractive index ranges from 1.560 to 1.568. The hardness on Mohs scale ranges from 6 to 6.5.
