Ex. University of Michigan Geology Department

Metacinnabar: HgS ; Idrialite: C22H14


The Metacinnabar is the black, granular material with the high luster. Also present are small, elongated crystals of red/orange Realgar. The Curtisite is a yellow/green color (see last photo) and not easily distinguished in visible light but fluoresces a bright green under SW. The specimen was acquired by the University of Michigan at least 50 years ago. The label for the specimen has been glued onto a thin piece of card stock which looks to be at least that old.

Condition: Good

Flaws: Nothing Appreciable
