Crystallized Gold 
Grass Valley, California
This extraordinary gold specimen is composed of highly lustrous crystal faces with curved striations. There are multiple areas of well-developed angular flat faces the surface reflects light twice as bright back. Also, the top portion is composed of sharp curved short but thick wire gold crystals. The color of the gold is a very saturated buttery yellow and the purity is above 95% purity in gold content. This high purity of gold in nature is very complex to obtain and very rare due to other natural elements that are present and hydrothermally brought up from within the earth.  This gold crystal is the most prime example of rare gold from its locality in aesthetics, color, brightness and purity.
