ML00325 - Gold
Round Mountain Mine, Nye County, Nevada, USA
miniature - 4.2 x 3.5 x 2.9 cm
$ 5000.00

This 3 dimensional gold specimen exhibits the buttery yellow color typical of golds from the oxidized zone. Important textures include rhombohedral patterns to the leaves that is explained by gold growing along calcite cleavage planes. On top of the leaves are numerous gold crystals with cubic and octohedral crystal faces.

ML00327 - Gold
Round Mountain Mine, Nye County, Nevada, USA
small cabinet - 5.3 x 3.6 x 2.5 cm
$ 7500.00

At first glance, one sees some shiny leaves completly covered with gold crystals. Upon closer inspection, one realzies that most of these crystals are well formed cubes, the larger of which are up to 0.5 cm on edge. Looking at this specimen, it is hard to believe that cubic gold is actually a rare occurance.

Round Mountain Mine, Nye County, Nevada, USA
miniature - 3.9 x 2.1 x 1.7 cm
$ 3000.00

This gold is typical of the intermediate zone located between the oxidized and sulfide ore. As with many Round Mountain golds, there are stacked cubes which have twinned off the primary leaf.

ML00330 - Gold
Round Mountain Mine, Nye County, Nevada, USA
small cabinet - 8.0 x 5.7 x 4.5 cm
$ 24000.00

This large matrix gold shows textbook epimorphic leaf growth along the previous rhombohedral calcite crystal planes. Second generation crystal growth sprouting off of the leaves adds texture and relief in the form of cube and octohedral gold faces.

ML00333 - Gold
Round Mountain Mine, Nye County, Nevada, USA
miniature - 4.7 x 2.7 x 2.0 cm
$ 10000.00

This is one of the best examples of spinel law twinned gold crystals on matrix ever found at Round Mountain. The crystals show slight hoppering indicative of rapid crystal growth.

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
small cabinet - 6.1 x 3.4 x 2.5 cm
$ 9000.00

ML00336 - Gold
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.

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.
