“12.8 x 7.4 x 6.0 cm. An impressive, very fine and rare large combination specimen from this extinct underground iron mine in the Upper Peninsula. Striking, slanted, parallel-growth goethite stalactites are coated with green chamosite, a Chlorite Group species. Scattered clusters of dogtooth, pastel-pink, manganoan calcite crystals and tiny sparkly pyrite crystals are a fine accent. The broken stalactites reveal the radial growth of the lustrous, acicular goethite. The calcite fluoresces pink. Choice, showy and rare material from the Schlichter and Robert Nowakowski Collections. ”
