Simply a masterpiece! Worthy of any museum worldwide. This exceptional specimen is from the Cumberland Mine in the Elmwood Gordonsville Zinc District, Smith County, Tennessee. Formerly in the Brian Stefanec and Travis Hartin collections. The condition is superb, no damage. The matrix is a block of limestone covered in dark lustrous sphalerite crystals studded with small double terminated honey calcite crystals. It measures 8 x 11.5 x 11 inches (20.3 x 29.3 x 27.8 cm) overall. The big calcite crystal measures 12 x 6 x 5.5 inches (30.4 x 15.2 x 14 cm). It is double terminated with several smaller piggyback double terminated side crystals. Will send more pictures if you're serious.
