Neptune Designs

Neptune Designs sits at 301 Duval Street, at the northern end of the road close to where it meets the waterfront near Mallory Square. The shop specializes in handcrafted jewelry built around ocean and Key West themes, and it has developed a particular niche in pieces made using authentic Atocha coins, the silver and gold coinage recovered from the wreck of the Spanish galleon Nuestra Senora de Atocha, which sank off the Florida Keys in 1622 and was famously salvaged by treasure hunter Mel Fisher in the 1980s.

Working with authorized shipwreck coins means Neptune Designs sells jewelry that is tied directly to Florida Keys maritime history rather than simply using a generic nautical theme, which is a meaningful distinction for collectors who specifically seek out treasure coin jewelry as a category. Because genuine shipwreck coins are a limited and historically documented resource, pieces built around them tend to carry more significance, and often a higher price point, than jewelry using purely decorative nautical motifs.

Visitors who have shopped here describe the staff as knowledgeable and willing to walk customers through custom design and ring creation options without a high pressure sales approach, which stands out in a part of Duval Street where high volume tourist traffic can sometimes push shops toward a faster, more transactional sales style. The shop also offers ear piercing services in addition to its jewelry sales, rounding out its offerings for visitors looking for more than a simple retail purchase.

Being positioned at the Mallory Square end of Duval Street puts Neptune Designs in the path of cruise ship passengers and sunset celebration crowds, giving it a different customer base than shops further south on the same street. That location also places it near several other jewelry shops covered in this directory, including Conch Jewelers and Emeralds International, both within a short walk, making this end of Duval a reasonably dense cluster for anyone specifically shopping for fine jewelry or shipwreck coin pieces during a Key West visit.

Because a phone number and independent website were not confirmed from the sources reviewed for this profile, visitors interested in Neptune Designs should plan to visit in person during typical Duval Street retail hours, or ask nearby shops and hotel concierges for current contact information if trying to reach the shop ahead of a visit. Given its focus on custom work and authenticated historical materials, allowing extra time for a visit, rather than treating it as a quick walk in stop, will likely make for a more useful shopping experience.
