From Sunken Treasure to Custom Jewelry: The Story Behind This Scuba Inspired Pendant
LISA
Creating a Custom Atocha-Inspired Diving Pendant
Some custom jewelry projects begin with aesthetics. Others begin with emotion, memory, and personal history. This pendant began with all three.
For years, this client has shared a meaningful tradition with his wife: each year, he commissions a new custom piece of jewelry for her. Over time, the tradition has become more than gift-giving. Each piece captures a chapter of their lives together, preserving experiences and passions in wearable form.
This year’s inspiration came from the underwater world they have explored together for the past five years through diving.
The Legend of the Atocha Shipwreck
As an avid diver, the client became fascinated with the legendary story of the Nuestra Señora de Atocha (watch the fascinating National Geographic video), the Spanish treasure galleon that sank in a hurricane in 1622 near Key West, Florida. Centuries later, treasure hunter Mel Fisher famously dedicated his life to recovering the wreck and uncovering the artifacts hidden beneath the ocean floor.
The discoveries became legendary: emeralds, gold and silver bars, Spanish treasure coins, and centuries-old artifacts preserved beneath the sea. Yet what resonated most deeply with our client was not simply the treasure itself, but the history and symbolism behind it.
During Spain’s colonial era, precious metals and jewelry often represented portable wealth. Coins, gemstones, and personal adornments could preserve value discreetly and travel across oceans in ways that traditional wealth could not. The idea of hidden treasure carried inside personal objects became an important emotional thread throughout the design process.
Why Spanish Treasure Coins Became the Centerpiece
Among the recovered artifacts, the client was especially drawn to Spanish cob coins.
Unlike modern coins made with perfectly machined dies, these pieces were hand-cut and individually struck, giving each one an irregular, organic character.
Their imperfections are part of their beauty.
The specific inspiration centered around the iconic four-rail Spanish coin design and crest patterning associated with shipwreck treasure.
An important detail of the project is that the coin used in the pendant did not come directly from the Atocha wreck. Instead, the client selected a coin with the same spirit, texture, and historical character that connected to the story he wanted to tell. It allowed the pendant to feel inspired by history without becoming a literal reproduction.
Once the coin was chosen, the next challenge became designing the surrounding structure.
Vintage Scuba Gear as Design Inspiration
The client specifically wanted the halo around the coin to evoke vintage scuba equipment—particularly the iconic double-hose regulators used in early diving systems in the 1950s and 1960s. He provided reference photos of vintage regulators whose ribbed breathing hoses became the foundation for the pendant’s outer form.
Our first design explorations focused on translating those vintage diving elements into jewelry form. Early concepts experimented with nautical emblems, anchor motifs, regulator-inspired framing, and the balance between historical treasure and underwater equipment. The challenge was to make the pendant feel cohesive rather than thematically costume-like.
Building the Pendant Through CAD Design
From there, the project moved into CAD development, where the regulator-inspired halo structure began to take shape around the irregular silhouette of the Spanish coin. The ribbed outer halo was carefully sculpted to echo the flexible hoses of vintage scuba regulators while still functioning as an elegant jewelry form. Structural details at the top and bottom of the pendant reference vintage dive hardware and connection fittings without becoming overly literal.
The resulting design feels mechanical, historical, and organic all at once.
The Meaning Behind the Finished Pendant
What makes this pendant exceptional is how many layers of meaning exist beneath the surface. It honors the client’s life underwater, references one of history’s most famous shipwreck treasure stories, celebrates the aesthetics of vintage scuba equipment, and continues a long-standing tradition of deeply personal annual gifts between husband and wife.
The final pendant became more than jewelry. It became a wearable artifact of exploration, history, craftsmanship, and shared experience—something that could only exist because of the story behind it.
