Our take on the Birkin bag- this fabulous sterling silver handbag locket is highly unusual and a standout piece. It has a sterling silver buckle, marcasite detailing and a collar of garnets. The handbag locket opens to take a secret message or a tiny keepsake and has an openwork back. One of Judy Murray's favourite pendants, the Birkin Locket is hallmarked by the Edinburgh Assay Office. Birkin Locket measures 28mm x 36mm.
