Herkimer Diamond Quartz, the water-clear double terminated crystals of Quartz that launched a thousand rockhounds! This freestanding four-crystal daisy-chained cluster has been carefully reconstructed, as almost all clusters are, from the individual crystals that were found adjacent-yet-disarticulated within the matrix. KOA, Herkimer County, New York, USA. 1.5" x 1" x 1.1", .6 oz.
