Sphalerite (Twinned) With Chalcopyrite
Oppu mine, Nishimeya-mura, Aomori Prefecture, Tohoku Region, Honshu Island, Japan
Miniature, 5.1 x 4.8 x 4.2 cm
Ex. Dr. Eugene Meieran
This is an old-timer, showing classic twinned sphalerites with a dark but translucent yellow-brown color. The intersecting sphalerite twins are perched on quartz, and accented with sharp and brassy golden chalcopyrite crystals. A fine display quality specimen from this very old mining district, long in the Gene Meieran sulfide collection (his label dates it back more than 30 years) .
