This is a vintage gold chain, which is 16″ (41cm) long and at least 1mm wide. It is of Continental origin, where 8 carat gold is the standard, and the catch is therefore stamped 333. The links are curved, and I think the official name of this type of chain is “curb link” chain. The chain weighs 1.66 grams. Everything is in excellent condition, and the chain has been sonically cleaned, ready to wear.
