A fine rhodochrosite and quartz thumbnail from the American Tunnel Mine of Silverton, Colorado. A nice cluster of lustrous, rose-red, complex rhodochrosite rhombs rest on an earlier generation of pastel-pink rhodochrosite and are beautifully highlighted by a couple of water-clear quartz needles. The rose-red rhombs are peppered with either a third generation of much lighter, micro rhodochrosite rhombs or calcite rhombs. Classic material from this noted locale from the Jaime Bird Collection.
