This fabulous sterling silver charm bracelet is part of my vintage jewelry collection. The gorgeous, delicate chain bracelet has textured links with a pair of ship's wheels charms and a U.S. Navy insignia charm.  All 3 charms are marked Sterling on the backs.  The bracelet is marked Sterling on the small loop attached to the spring ring clasp.  It measures about 7 7/16" long; the largest links are 5/16" long.  The ship's wheels are about 9/16" diameter x 5/8" high.  The USN charm is about 1/2" wide x 5/8" high.  Total weight is approximately 4.4 grams.  Exact time period unknown - probably WWII era?  Great vintage condition, consistent with age and use; clasp works well.  If you love delicate beauty, this charm bracelet is for you!!  Feel free to ask questions.
