On the Way to Cape May: The Search for Cape May Diamonds

“On the way to Cape May, I saw my dreams come true.”

This seaside serenade made famous by Al Alberts sings of summertime romance along the beaches of New Jersey. Cape May, New Jersey, invites guests to take a step back in time and explore “The Nation’s Oldest Seashore Resort.” Over 600 lovingly preserved Victorian buildings are the crown jewel of this National Historic Landmark. However, your visit won’t be complete until you find a handful of illustrious Cape May Diamonds.

“Diamonds” in the rough

Cape May Diamond expert Jeanette Fox Bartolomeo of Sunset Beach Gift Shops explains. “These beautiful gems we call Cape May diamonds are pure quartz crystals,” she says. “They are, in fact, semi-precious stones with a hardness of seven compared to a genuine diamond’s hardness of 10. Just like real diamonds, they are hard enough to cut glass.” When polished, cut, and faceted, Cape May Diamonds resemble an actual diamond (at a fraction of the cost).

The largest faceted Cape May Diamond, weighing in at a staggering 1,800 carats, along with several smaller ones, are on display at the Cape May County Museum.

A connection to the Ice Age

Over 10,000 years ago during the Ice Age, massive ice sheets covered much of North America including New Jersey. These thick glaciers trapped rocks and sediment and, as the ice melted, quartz pieces began their long journey tumbling toward the sea. Cape May quartz travels from the swift water of the Delaware River towards the Delaware Bay and into the Atlantic Ocean.

A gift of goodwill from the Lenni-Lenape tribe

Bartolomeo shares the Cape May Diamond’s connection to the Lenni-Lenape Native Americans here in New Jersey. “Cape May Diamonds were first discovered by the Kechemeche Indians, part of the Lenni-Lenape Council,” says Bartolomeo. “The diamonds were found in limited areas around Delaware Bay. The translucent gems were held in high esteem by the Kechemeche who attached mystical powers and a sacred trust to their possession. They believed the curious stones possessed supernatural powers, influencing the success, well-being, and good fortune of the possessor.”

Searching for Cape May diamonds: the lure of Sunset Beach

There’s something magical about Sunset Beach—one of few places on the east coast where the sun sets on the water. Located where the Delaware Bay meets the mighty Atlantic Ocean, Sunset Beach is located at the southernmost tip of the Cape May peninsula.

While the sunsets are spectacular, beachcombers flock to Sunset Beach to search for Cape May Diamonds as this location is abundant with them. Plan to wear shoes of some type as the beach is predominately pebbles. The best treasure washes up after the ocean has been churning from a storm. However, Cape May Diamonds can be found at any time. Just look for the clear, glistening quartz among the pebbles. Some “diamonds” appear more like frosted sea glass. As with any gift from nature, Cape May Diamonds come in all shapes and sizes. Bring a sand scooper to dig down past the top layer as the stones can be hidden.

In addition to Cape May Diamonds, beachcombers find sharks’ teeth, agates, Indian arrowheads, and black quartz.
