This thumbnail specimen consists of well over 100 tightly packed, intergrown hexagonal prismatic Vanadinite crystals resting on an indiscriminate base. These crystals range in size from nearly microscopic (less than 1 mm in any dimension) to 0.3 x 0.3 x 0.2" (8 x 8 x 5 mm). All are incomplete and have somewhat warped form, but their hexagonal outlines are often visible (see the close-up image) and they have rather unusual, rounded hexagonal pyramidal terminations; several even show evidence of being double-terminated. Their color is a moderate reddish-orange (though it seems to vary a bit according to their size), and they are all dimly to moderately translucent and have a vitreous luster. The host rock's makeup is hard to determine, as it is almost completely covered with either the Vanadinite crystals or a thin, black coating on top of which the Vanadinites rest.
