A single complete Cinnabar crystal rests in a quartz-lined hollow on this specimen. It is the only complete, undamaged crystal on the piece. It has dimensions of approximately 0.3 x 0.2 x 0.2 (0.8 x 0.8 x 0.5 cm) and has an excellent trigonal prismatic form with a steep trigonal pyramidal termaination. It appears to be a penetration twin, judging by the protrusions that extend from the termination faces. It has the standard deep red coloration and bright, adamantine luster, and shows some noticeable transparence under bright light. There are several other red patches around it, denoting broken crystals, and the quartz bed on which they rest consists of scores of tiny hexagonal prisms that are colorless and quite clear. There is a small formation of white crystalline dolomite or calcite nearby, and the host rock is likely a limestone or calcareous shale.
