Labradorite Tumbled Stones - Medium 20 - 30 mm - 1 LB - Madagascar Pouches Semiahmoo and other Coast SalishLABRADORITE Labradorite ((Ca,Na)(Al,Si)4O8), a feldspar mineral, is an intermediate to calcic member of the plagioclase series. It has an anorthite percentage (%An) of 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
