Outstanding large group of very well-formed Columbite-(Fe) (to 6+ cm!) and Samarskite-(Y) crystals from the Spinelli prospect, Glastonbury, Hartford County, Connecticut, USA. This is one of the best columbite specimens known from this locality, and was found as part of a 2008-2013 specimen mining project at this now-extinct locality. Truly exceptional for this species at the locality, one of the very best!! Ex. Eric Quinter, Tony Albini Collections.
