An EXCELLENT and showy plate richly covered with lustrous, chocolate-brown staurolite crystals to 1.2 cm from the famous Franconia Mine at Lisbon, New Hampshire. This fine piece is very nearly pristine, with only a couple of bruised crystals, which are barely noticeable. Ex Richard Hauck Collection with two, fine, old labels. 9.3 x 5.8 x 3.1 cm
