||Twinned Calcite on Sphalerite
Elmwood Mine, Carthage
Tennessee, United States
12 x 10 CM (cabinet)
Perfect jewel-like amber cognac color calcites (largest is 7.7 CM) set on a dark red to black matrix of crystalized sphalerite. No damage and only one tiny contact on one of the smaller calcites, this is a pristine piece that has top notch luster. The main crystal is the sort of twin sometimes described as a "frog" where one half of the twinned pair develops selectively and makes a froglike crystal. An Elmwood classic that is far better than you could usually expect in this price range.
