This calcite is from the Elmwood Mine in Carthage, Smith County, Tennessee, Ba-F-Pb-Zn District, Tennessee, US. This mine contains three shafts called the Elmwood, Cumberland, and Gordonsville. It has an entry slope called the Stonewall. They contain eleven different minerals including sphalerite which is the main ore mineral. The calcite is a common gangue mineral associated with the sphalerite. This specimen is a translucent to transparent double terminated complex calcite crystal resting on a secondary crystal. The upper termination has a slightly cleaved and healed surface which is typical for the calcites from this locale. The secondary crystal has a cleaved/healed base and the termination has fluorite crystals attached. There are inclusions of chalcopyrite present. This piece measures approximately 5 x 4 x 2 1/2 inches or 127 x 102 x 64 mm.
