A dramatic and aesthetic silver on calcite specimen from the famed New Nevada Mine at Batopilas, Mexico. Two, side-by-side, elongated, spinel-twinned silver "feathers" are beautifully upright on the front of the piece, The longest twin is 2.2 cm. Another, very slender twin, 1.4 cm, with a branch is very well-placed at the end of the calcite matrix. Many smaller "feathers" add to the overall beauty of this piece. The silvers have a very nice patina.
