While Albite is a rather common and mundane mineral from many points of view, this specimen has a few very attractive aspects to it. The Albite occurs in the triclinic form, and makes up a large mass through the intergrowth of three smaller masses; these smaller masses are composed of many small intergrown prismatic crystals that are generally aligned in a single direction. They have a pale beige color and a pearly to waxy luster. None of their visible dimensions exceed 0.5" (1.3 cm), and more than 50% of each crystal's volume is obscured through their intense intergrowth. They form a crust that seems to rest on a mass of rather finely-grained Albite that is intermixed with equally fine smoky quartz crystals or fragments. Resting on top of the Albite crust is a smoky quartz crystal that is in excellent condition and appears to have no damage. It is in the hexagonal prismatic form, and its prism faces are sloped so that it almost appears to have the "Tessin Habit", but there are very small termination faces near its tip. It has a pale brown color and is transparent and mostly quite clear, though it clouds up a bit right near its base. Along with this quartz crystal is a thin, radiating cluster of many thin, long epidote crystals. They appear to be in good condition and range in size from 0.4- 1.0" (1.0- 2.5 cm). Their color is a moderately deep forest green with a bit of a yellowish hint, and they show definite transparence. The epidote and smoky quartz are situated a few inches away from and at right angles to each other, so they do not really make the specimen seem unbalanced. Altogether, it is a very attractive piece.
