Nestled among short quartz crystals in a hollow in the host rock of this specimen lie about 6 Rhodochrosite crystals. They occur in a short trigonal prismatic form that actually makes one think of garnets, as their form appears dodecahedral. The largest of these crystals is very exposed on the edge of the hollow; it measures about 0.2"(5 mm) in diameter and has a rose-red color, good crystal form and considerable damage to the most exposed side, so that it is not quite complete. It is transparent, however, and shows exceptional clarity where it can be determined. The other crystals are similar in color and quality, but smaller. There are many fractured and incomplete crystals around the edge of the hollow. The quartz that lines the hollow has good form and decent clarity, with a small amount of cloudiness at the center of each crystal. The hollow is set into a host rock that is likely made up of low-grade manganese oxides and silicates, along with a few tiny flecks of metallic sulfides.
