Purple Labradorite palm stone, high quality mineral, great flash pollished specimen, Labradorite rock Agate Drilling into underground sandstone formationsLabradorite, a feldspar mineral, is an intermediate to calcic member of the plagioclase series. It has an anorthite percentage of between 50 and 70. The specific gravity ranges from 2. 68 to 2. 72. The streak is white, like most silicates. The refractive index ranges from 1. 559 to 1. 573 and twinning is common.
