Sphalerite on Calcite with Tennantite

92 x 86 x 42 mm

Sharp, tetragonal crystals of gemmy, translucent yellowish-brown Sphalerite to 24 mm are nestled on a matrix of chalky-white, flattened scalenohedrons of Calcite to 41 mm dusted with brassy Chalcopyrite. A few shiny black Tennantite crystals to 11 mm are also present. In excellent condition, this is a fine and aesthetic old-time Sphalerite raised over 30 years ago.
