Cinnabar is the chief mineral composed of the element mercury, and is a very important ore mineral. Though most Cinnabar is massive and uninteresting in habit, several localities produce phenomenal and strikingly colored red crystals that stand out with beautiful contrast on top of a white matrix.

Cinnabar is occasionally associated with Native Mercury, in the form of small metallic blobs perched on top or within cavities of the Cinnabar. Since Cinnabar is composed from mercury which has various health hazards, it is recommended to wash hands after handling Cinnabar specimens.
