This phenomenal Swiss enamel locket necklace is fashioned in 18k gold and dates to the mid 19th century. Each hollow link of the chain is beautifully enameled in blue and black with a lovely decorative clasp stamped with French import marks. The locket is held closed by a tiny functional padlock. It can easily be opened to add your own photo small memento by using the petite key suspended on a length of fine gold chain.
