Sunnyside Mine, Bonita Peak, Gladstone, Eureka District, San Juan County, Colorado - The Sunnyside Mine produced some very well known Rhodochrosite specimens in its history, along with some attractive association pieces. This specimen features sharp, well-formed, attractive rhombohedra of notably RED colored Rhodochrosite which are associated with Quartz on matrix. The largest Rhodo crystal measures 7 mm, but the most imporant aspect is the RED color of the rhombs, as the vast majority of Sunnyside Rhodos are a shade of pink, and red crystals are very hard to find. Beautiful, classic material and is a true staple of any good Colorado collection. From the worldwide collection of noted Idaho collector Geary Murdock.  Overall size is 5x3.5x3 cm
