Copper, Prehnite
Cabinet, 10.0 x 7.2 x 5.5 cm
Keweenaw Co., Michigan, USA
A SHOWY, old-time, Michigan Copper Country CABINET specimen of tiny, sharp and lustrous, tetrahexahedral copper crystals to 2 mm on preferentially-coated, translucent and lustrous, botryoidal, pastel-green prehnite on matrix. RARE MATERIAL, indeed! If not for the tiny associated copper you would NEVER guess Michigan could produce such beautiful large masses of prehnite. I certainly had never known.
