Item Description

Two intergrown calcite rhombs are aesthetically sprinkled with splendent, jet-black, twinned, sphalerite crystals on this showy, excellent and classic combination specimen from Naica. The rhombs are actually colorless, glassy and translucent, but have a secondary overgrowth of a creamy calcite druse. Complete all-around and pristine. Fine material from the Dick Heck Mexico Collection.
