From the BGB Jewelry blog: Fun fact-- Sailors would get a swallow tattoo when they'd traveled 5,000 nautical miles. Over time, the image has come to represent freedom, hope, a return to safety and love for family. This Sterling Silver Swallow Necklace is a great way to share the sentiment without getting a permanent tattoo. Hanging on a 17" chain with a lobster clasp closure. What a perfect addition to your jewelry collection!
