This specimen of albite shows the pattern of loosely stacked thin plates called "clevelandite". The specimen appears white and opaque, with a vitreous luster apparent on flat surfaces. However, a loupe reveals that the crystals are actually transparent and nearly colorless, with an interesting growth pattern on the surface that when added to the myriad internal fractures gives the specimen a nearly white appearance.
