5.5" Sphalerite, Quartz and Calcite Association - Elmwood Mine

This is a 5.5" wide specimen containing sphalerite crystals with sparkling quartz and a large, twinned calcite crystal, collected from the famous Elmwood mine in Tennessee. The largest calcite crystal measures 5.5" long.

The Elmwood Mine is a zinc mine in Carthage, Tennessee that opened in 1969. It then closed for many years, only to be reopened in 2010. It has produced many world class specimens of fluorite, calcite, barite, and galena over the years. Specimens used to be plentiful as miners were allowed to recover specimens, but collecting is strictly prohibited by the new mine owners. They've gone to great lengths to prevent the mining of specimens, including blasting crystal pockets or filling them with slurry.

Shalerite ((Zn,Fe)S) is a mineral that is the chief ore of zinc while Galena is a primary ore for lead.
