This necklace would make a lovely, romantic gift. It is made of sterling silver and rose gold plated (stamped 925). The envelope charm opens to reveal a small compartment for a mini love note or photo. The chain measures 18 inches long and has a standard lobster clasp closure. Please see photos for size context. There is only one available. I am open to offers :)  *These photos were taken by me and show the actual product being sold. Thanks for looking!
