|LABRADORITE FELDSPAR MINERAL FACTS|
|The Gem and Mineral Collector's Photo Gallery by Nevada Outback|
Labradorite Mineral Facts:
Grey, brown, green, reddish, rarely colorless.
Cleavage: The usual feldspar cleavage; perfect parallel to basal plane, less perfect parallel to brachypinacoid.
Luster:. Vitreous luster that is nearly pearly on the cleavage planes. It is transparent to opaque.
Structure and Associated Minerals:
The twins in Labradorite are like those of albite, but the twins are usually in broad lamellae as opposed to the finer lamellae of albite. In weathering it alters to epidote, and in some instances into scapolite, and very commonly into the mixture known as saussurite, which is an aggregate containing zoisite or garnet as its most important component.
