This good sized Herkimer Diamond crystal has one termination that is almost bisected by a deposit of dolomite; and one that is indented with a series of depressions and ‘keys’, showing where it was once part of a small cluster. There are a few other superficial groundmass deposits and black traces of anthraxolite; and some deeper regions of veiling and internal fracturing.
Size: 2.25 x 2 x 1.5cm
