In the Victorian language of flowers, the buttercup means cheerfulness. This lovely rendition is unmarked but tests positive for gold of 14k. It is beautifully made with textured petals and the stamens are very realistic. The flower is one inch across. The back has an old style tube hinge and c catch and also a pendant bale that is on a hinge, always a sign of quality! This pin weighs 4.2 grams and is in nice condition. C. 1880 and American.
