Crystallized Gold
Agua Fria, Mariposa, California 
 
An exceptional example of spinel twinned gold, this specimen displays an intricate arrangement of branching, twinned geometric crystals. The crystals have naturally stacked together, producing remarkable depth and a bold three dimensional appearance. Thick crystalline growth extends across nearly the entire surface, complemented by good luster and a consistent buttery yellow color. Specimens with this degree of crystal development and pronounced spinel twinning are rarely available from this locality.
