This small hand specimen consists of about 8 hexagonal prismatic Amethyst crystals that rest on a basalt base. These crystals reach dimensions of 1.0 x 0.4 x 0.4" (2.5 x 1.0 x 1.0 cm) and are generally in very good condition- two of them are damaged and incomplete, but the rest are intact. All have excellent form, with well-defined edges and clean, smooth faces that possess the standard vitreous luster. Their color is a pale violet at their terminations but fades to colorlessness near their bases. Likewise, they are transparent and show good clarity at their terminations, but cloud up with veil-like inclusions near their bases. All show evidence of inclusions near their terminations, however; most of these consist of oddly-shaped air- or water-filled inclusions that are trapped at the bases of their terminations. The largest of these crystals contains a two-phase inclusion, as an air bubble is visible inside the inclusion. There is a thin crust made up of intersecting clusters of tiny, white crystals at the bases of some of the Amethysts- I do not know what they are made of. The basalt base has a greenish-gray color and contains many irregularly-shaped hollows, most of which are filled with a dull, rust- or cream-colored material that I also cannot identify.
