This is a gorgeous Edwardian pin in sterling silver with guilloche enamel. It is by Charles M Robbins and it marked Sterling Champleve with the Charles M Robbins mark and English hallmarks. The brooch is very lovely and delicate - white with delicate pink flowers and green leaves.
It measures about 2 inches by about 3/4 inch. It is in very nice condition with a flake to the clear enamel at one end of the brooch. This can be felt but is hard to see and does not detract from the piece.
