Where to Find Quartz in New Jersey
New Jersey quartz concentrates around Franklin and Sterling Hill in Sussex County, where the famous zinc deposits carry secondary quartz in marble and pegmatite. The Buckwheat dump and the Sterling Hill museum collecting ground yield small quartz crystals on franklinite and willemite matrix. The Trotter shaft area produces clear and milky quartz alongside the fluorescent assemblage. Trap-rock quarries through Hudson and Bergen counties (Prospect Park, Paterson, Great Notch) carry small quartz crystals in basalt amygdules with prehnite and pectolite. Most New Jersey quartz is small and matrix-bound; specimen value lies in the rare associations.
