Betafite is a strange brew of uranium, titanium, and niobium, a member of the pyrochlore group of species. This is a huge, floater betafite crystal with pretty good aesthetics for a "rare earth ugly"; and also unusually complete and symmetric for a large crystal. Although not from the type locality mine for the species, this is from the same pegmatite deposit.
