Rhodochrosite -rare Colorado locale
Idaho Springs, Clear Creek County
3 x 2.8 x 1.5 CM (small miniature/ large thumbnail (toenail))
A single rhomb crystal with fine deep red color from a 1960 find in Idaho Springs. Similar to the better know localities of Sweet Home (Alma) and American tunnel (Silverton this came from an unidentified mine (likely the Moose mine or any of several Central city sites). The collectors were the Hitchings (father and son team) on a family trip from Massachusetts to Colorado. They collected 7 specimens from a boulder in a dump, this being the largest rhomb. They were not sure of the mine name and recorded these only as Idaho Springs.
Simply a killer with perfect form, zoned crystals are arranged in a radiating cluster. These three species are found together as zoned sections of individual crystals at this site. This find at Huanggang (Inner Mongolia) have redefined these species and are widely regarded as the worlds best. The tips of these crystals are translucent and show some internal zoning but the overall display quality of this piece is why this is so exceptional. Helvite and Genthelvite are fairly rare but known from several locales. However good Danalite is ultra rare worldwide these rank as world class crystals.
