McDermitt Mine (Cordero Mine; Old Cordero Mine), Opalite District, Humboldt Co., Nevada, USA
Miniature, 5.0 x 3.0 x 3.0 cm
Kleinite is a very strange mercury nitrogen chlorosufate of unusual chemistry, and is known at its best in crystals such as these from this rather remote locality. This is a specimen self-collected by a friend of mine over a decade ago and is one of the best I have seen for sale. It's attractive, too! 5 x 3 x 3 cm
