Thumbnail, 1.5 x 1.5 x 1.0 cm
Colorado Mine (Colorado Quartz Mine), Colorado, Whitlock District, Bagby-Mariposa-Mount Bullion-Whitlock District, Mariposa Co., California, USA

A SUPERB gold thumbnail from the Irv Brown Thumbnail Collection and the Colorado Quartz Mine. Ultra-bright and super-sharp, golden-yellow octahedrons are very pleasing set on carpet of leaf gold. The crowning 6 mm octahedron is a stunner and I like the enechelon character of the smaller octahedra on the "tail."
