Locality: Coleman Mine, near Jessieville, Hot Springs Natl Park, Arkansas. Size Class: Large Cabinet. Collection: Schertz Collection. With dramatic large crystals to 18 centimeters, and in as close to pristine condition as one can ask on a huge quartz specimen, this is a significant piece from Arkansas. Most crystals in such large clusters have extensive damage or polishing, and this usually renders them second rate, compared to quartz from Brazil. However, this piece is an important, old Arkansas specimen that has quality as well as locality value going for it. It was originally mined by Jim Coleman of Coleman Mines. 19.6 pounds. Size 34.5 x 30.5 x 20.0 cm.
