Cape May Diamonds: The Story Behind the Shore Stones
Cape May diamonds are not diamonds. They are quartz pebbles made smooth by water and time. Their path links inland geology to Delaware Bay and gives a simple beach walk the pleasure of discovery.

Four useful lenses
Choose by the experience you want
The right answer depends on the shape of the day. These four lenses make the tradeoffs visible before a reservation or drive.
What they are
Clear or pale quartz pebbles, often rounded and polished by natural movement.
Where people look
Sunset Beach is closely associated with them. Conditions and beach rules matter.
How to identify them
Look for translucence and a glassy quality when wet. Not every pale stone is quartz.
What to do with one
Keep a modest souvenir where permitted, or have a piece polished by a local shop.
Let geography do part of the planning
Cape May City is compact, but the larger Cape May area is not one walkable neighborhood. The oceanfront, historic center, harbor, West Cape May, Cape May Point, North Cape May, and county attractions each create a different route.
Group stops that belong together. Walk within the central city. Save the car for the Point, Delaware Bay, airport, ferry, farms, and county destinations. A calm route leaves more time for the reason you came.
