ML00334 - Gold
Round Mountain Mine, Nye County, Nevada, USA
small cabinet - 5.9 x 3.6 x 1.6 cm
$ 15000.00

The undulatory nature of this golf leaf is the result of distortion within the vein due to Basin and Range faulting. The net result is that the lustrous twinned crystals along the face of the leaf reflect light sequentially as the specimen is rotated. This is one of my all time favorite specimens from the mine.

Round Mountain Mine, Nye County, Nevada, USA
miniature - 3.9 x 2.0 x 0.8 cm
$ 1400.00

Some golds from Round Mountain require very little cleaning. This specimen had only a small amount of sericite clay that was washed off in order to expose these large hoppered octoheral crystals on the edge of the leaves.

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.

ML00338 - Gold
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.
