- Baryte, Sphalerite
- Cumberland Mine, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA
- Cabinet, 14.6 x 10.5 x 6.7 cm
Classic baryte "balls" to 5.8 cm with clusters of lustrous, ruby-jack sphalerite are dramatically set on the two-sided, wedge of sparkly, drusy quartz-covered limestone matrix on this very impressive cabinet specimen from the less common and now-closed Cumberland Mine of Tennessee. The Cumberland is very near to the Elmwood Mine and was not known as a great specimen producer. Baryte and quartz are rare from the Cumberland, so this is an exceptional combination specimen from this locale. Ex. Walt Gaylord Collection: mine geologist for the Elmwood and Cumberland Mines. His note indicates that the piece was collected in 1994 from O6S #4 within the mine.
