On a gray and white host rock rests a single, large, and nearly perfect twin crystal of cinnabar. The crystal has six ridges jutting to the point of the crystal, and each ridge terminates to a crystal face that tapers in towards the base of the crystal (rather like a 6-sided arrowhead). The cinnabar is very translucent and blood red when a bright light illuminates it from the rear. The surface appears slightly darker than the interior, judging by the light damage on the ridges and point. The host rock appears to be something gray covered with tiny quartz crystals (it may be simply quartz with black inclusions), plus a fair amount of white dolomite crystals providing a nice contrast for the cinnabar. The cinnabar crystal is classic in shape, well-formed, and measures 11mm from exposed base to tip and 10mm across.
