Sunset Beach at the tip of Cape May is the classic place to hunt Cape May diamonds, rounded pure quartz pebbles that polish up like gemstones. The quartz travels roughly 200 miles down the Delaware River from veins in the upper watershed, arriving water-clear and wave-worn on the Delaware Bay shore. It is a free, beginner-friendly beach with easy pickings after storms. Reported finds include quartz, chalcedony. Below: coordinates, access notes, nearby spots, and trip-planning links.
