Here is a pretty white enamel butterfly pin from David Andersen, Norway's best-known jewelry maker. The pin has white guilloche enamel on the wings and a black enamel body. It is marked "D-A 925S (hallmark) Norway-Sterling" on the back. This pin has a safety catch and probably dates from the 1970's. It is in excellent original condition with pristine enamel. It measures 7/8" X 1 1/4."
