Herkimer Diamond (Quartz)    Middleville, New York. Ex. Dawne and Paul Dunning collection.  An exceptionally fine example with a larger crystal and small rider.  3 x 2.2 x 2.1 cm overall.  This one is almost perfectly clear.  A couple very tiny anthraxolite specks and a couple very tiny dissolution spots on the surfaces (one on rider and one on main crystal).  No damage.  Very nice for this price.  $170
