The listing, Two-Tone Mariner Link Chain, 18", New has ended.
Gold/silver tone mariner link chain, 18" long, lobster claw clasp. I believe the chain is gold plated, but the only lettered hallmark I can read is "XP". There are three other marks; one appears to be a geometric symbol of some sort, the other two are identical, and they are tiny pictures. All markings are on the links that connect to the clasp. This is a new chain, shiny and elegant.
