This is a gorgeous and sparkly oval shaped diamond and black onyx locket in sterling silver. It is a pre- owned item in great condition and is vintage. The locket can hold two precious pictures and is an enhancer, so it should fit most chains, and chain isn’t included. I am not sure of the diamond weight but the front looks pretty impressive and are full of beautiful sparkly diamonds. The brand is Affinity Diamond.
