A sparkling, jewel-like Naica fluorite that is just "different" than most! Superbly emplaced on matrix is a cluster of glassy and gemmy, colorless fluorite crystals, to 2 cm across. They, in turn, are associated with highly lustrous, brassy yellow pyrite crystals, to 2 mm across - a nice contrast. The non display side is festooned with lustrous, black sphalerite crystals, to 2 mm across. A gorgeous, unusual miniature from a productive mine, that stands above the crowd.
