Yaogangxian Mine Clusters Size:BACK ROW LEFT CENTER LEFT: 2" x 1Amazing collector's pieces from the Yaogangxian Mine famous for their fluorite and unique specimens. Most of these have quartz on them, but each is special in their own way. Back Row Left: Double terminated quartz cluster with fluorite, hematite, and arsenopyrite with growth interruptions and coating on back. The fluorite is UV reactive. Would really shine in a little stand! Back Row Right: Mostly quartz with a little calcite on it with arsenopyrite
