The Columbite crystal on this specimen from Biermann's Quarry in Bethel, Connecticut is large compared to other crystals from the locality. Once quite a prolific locality, this quarry is now very much picked over and is technically off-limits to collecting because it resides within a state park. This specimen is a generous gift of Elmore Easter to me. Crystal Size: 2.4cm x 0.5cm
