A highly unusual and very fine pair of intergrown, spherical calcite crystals nicely accented with gemmy, ruby-jack sphalerite crystals. The frosted, translucent calcites have a rich, golden-honey color when backlit. This is old-time, pristine material from this historic district and is from the very much less well-known Leopard Mine of the Picher Field. A striking and strange calcite specimen from the George Feist Collection # 1440. It looks like a fossilized dinosaur egg.
