Crystallized Gold
Agua Fria, Mariposa, California 
 
This exceptional spinel twinned gold crystal displays an intricate network of branching crystals formed by naturally stacked, twinned cubic growth. Bold, chunky geometric crystals cover nearly every surface, creating impressive depth and complexity. The native gold exhibits good luster and a rich, even buttery yellow color. Specimens combining such pronounced spinel twinning, substantial crystal development, and vibrant color are rarely encountered from this locality, making this an outstanding collector's specimen.
