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. The most productive ground is in Sterling Hill / Buckwheat dump (Sussex County), Franklin Marble (Sussex County), Paterson and Prospect Park quarries (Passaic County).

Casual hand collection of common rocks and minerals like quartz is allowed on most BLM and U.S. Forest Service land in New Jersey, with daily and annual limits set by the local field office. National parks, most state parks, and tribal land are off-limits. Always confirm rules before a trip.

Sterling Hill / Buckwheat dump (Sussex County) is the standout. Other strong ground includes Franklin Marble (Sussex County), Paterson and Prospect Park quarries (Passaic County).
