ML00337 - Gold
Round Mountain Mine, Nye County, Nevada, USA
miniature - 4.0 x 2.5 x 1.3 cm
$ 2100.00

At first glance, this specimen appears to be a mass of inter-grown gold crystals. Closer examination shows that many of the crystal faces are in optical continuity. Therefore, an argument can be made that these are all part of the same larger crystal.

Round Mountain Mine, Nye County, Nevada, USA
miniature - 4.5 x 4.0 x 2.9 cm
$ 10000.00

Two intersecting leaves are surrounded by an amazing number of cubic gold crystals. Individual cubes measure up to 6mm on edge, but it appears to me that these are actually hoppered growth of a cubic crystal that is closer to 2cm on edge.
