Put your love for the sea on display with a medallion-style necklace from Guy Harvey Jewelry. If you simply love nautical themes, take a look at the pirate emblem and maritime shield necklaces. You might also opt for a gemstone medallion in a nautical-style setting. Guy Harvey Jewelry also offers a number of medallions featuring sport fish, including marlins, dorado, sailfish and tuna.
If your enthusiasm is not limited to the water, take a look at necklaces with tropical birds, such as macaws and hummingbirds. Most necklaces are made from sterling silver, and you have the option of an all-metal or enameled background for many designs.
