(Hg₂N)(Cl,SO₄)·nH₂O

Micro yellow crystals of this rare mercury nitrogen chlorosufate are well displayed on the surface of these three specimen. The color will change to a darker, more orange color when exposed to light and then revert to yellow when put back into the dark. There are well formed small yellow crystals mixed with a more orange colored crust. This orange colored crust looks considerably different in habit and is likely a different species. A possiblilty is Radtkeite Hg ₃S₂ICl for which this is the only known location.

Condition: Good

Flaws: Nothing Appreciable
