Calcite, Elmwood Mine, Carthage, TN, USA
description: The calcite crystal twin is 5" tall (without matrix). Ex Keith Proctor and Dr Steve Neely collections. I obtained this piece in a trade with Keith Proctor in early 2006. In this trade, Robert Sielecki acted as my agent since I was unable to attend the 2006 Tucson Show in person as a result of business commitments. This piece displays a lustrous, symmetrical, gemmy calcite twin with a pleasing color which is beset elegantly in the middle of a chert matrix. Note the twinning line in the midsection of the crystal twin. The twin is perfect aside from a minor rub near the twinning line - the "rub" is easier to feel than what it is to see. The Elmwood Mine was at its heyday during the 1980's and during mining in this era, large pockets with crystals too large to remove were encountered. Later efforts to work the mine primarily for mineral specimens were with limited success. Despite the profusion of calcite from Dal'negorsk and China that has continually appeared on the market since the early 1990's, it could still be argued that Elmwood is the world's best calcite localy. There is absolutely no doubt that the Elmwood Mine has produced the finest calcite specimens in the Americas. Another Elmwood calcite that is part of my collection is a 2 3/4" twin on a small knob of sphalerite. The other piece is presently stored in Arizona.
