Our aim is your satisfaction. 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 2.68 to 2.72. The streak is white, like most silicates. The refractive index ranges from 1.559 to 1.573. As with all plagioclase members, the crystal system is triclinic, and three directions of cleavage are present, two of which are nearly at right angles and are more obvious, being of good to perfect quality.
The third direction is poor. 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. Your feedback is very important for us. We try to give our customer the best quality.
