1.65" Twinned Calcite Crystal with Sphalerite - Elmwood Mine

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.
