MF47E7: From a locality that used to be very productive (although it is no longer so) this one stands out from all the others found there for various reasons: the form of the crystal (slightly oblong and with small octahedral modification on the corners), all the faces are undamaged, the brilliance of the faces, and, above all, its great position on the matrix of botryoidal Pyrite. So while many Galenas have been found in the Tri-State district this one is special.
