Kleinite: Hg2N(Cl,SO4)·nH2O, Corderoite: Hg3S2Cl2 - Type Location
The Kleinite is the yellow to yellow/orange colored crystals and has the unusual property of darkening when exposed to light but reverting to the original color when placed in the dark. The Corderoite is a darker orange color. There is mention on Steve Pullman's label of two other possible species. There are a number of species from the location in the yellow to orange range, some of which are quite rare. One very likely possibility is Schuetteite. The Cinnabar is found on the bottom of the specimen as red inclusions in the host rock which is either Chalcedony of common Opal and as a small, darkened crystal (sorry no picture of the bottom, I just discovered the Cinnabar while writing this description).
Condition: Fairly Good
Flaws: There are bruised areas on the surface of the specimen.
