This small hand specimen consists of two partly intergrown clusters of radiating prismatic Epidote crystals. These crystals do not exceed 2.4" (6 cm) in length, and are generally in fair condition, as most are broken and missing their terminations. Those that are intact, however, have good monoclinic prismatic form, with well-defined edges and clean faces that possess a vitreous luster. The largest intact crystal shows obvious evidence of twinning, as can be seen by the striations on its "basal" face. All have a deep greenish-black coloration and are essentially opaque. There is one large, amorphous piece of broken quartz attached to the clusters and a few tiny crystals scattered elsewhere, but no other base or host material is present.
