Hübnerite, Rhodochrosite, Quartz - Sweet Home Mine, Mount Bross, Alma District, Colorado, USA
 
 Rarity from the famous Sweet Home Mine in Colorado. Highly aesthetic paragenesis of hübnerite and rhodochrosite on quartz crystals. The sharp-edged 14 mm long hübnerite crystal has a metallic luster and shows an intense red in transmitted light. In contrast, pink-red rhodochrosites with perfect transparency sit between the water-clear quartz crystals. A rare and wonderful collectors piece from the USA.
