Vintage Delft Porcelain Sterling Frame Brooch

Offered is a lovey classic vintage Delft porcelain sterling brooch.  The oval shaped cabochon features the blue on white windmill and sailboat scene popular in Dutch jewelry for decades. This measures 1 3/4″ x 1 1/8″ across the widest points of the ornate metal frame.  This portion is unmarked but tested to be silver. It has a old type C clasp.  The back of the domed pottery portion appears to be faintly marked Delft. The jewelry is undamaged.
