My cameo is on a silver pendant with no hallmarks. It's a cameo locket with 3 lady's. The lady in the middle has her back turned and has her arm's round the other two girls. they all turn there head to face the front of the pendant. I've seen the design on a black cameo but not seen one like mine, could you please tell me what you think as i have no clue.
