OMR11 Copper
Mountain City Mine, Mountain City District., Elko Co., Nevada, United States
6.8x 4.3x 2.1 cm

An excellent example of copper from Nevada.  At first glance, it would be easy to mistake this as being from a more famous copper locality (say, in Michigan) but this is a considerably rarer example.  

This is decently sized for the location, and shows very good crystallization.  Most interesting however, are the narrow, exaggeratedly elongated crystals that almost look like wires.  Unlike silver, copper does not usually form wires (and again, these look like hyper-elongated crystals, not wires) but to see any copper with that appearance is highly unusual.
