Vintage Bond Boyd GF Trillium Brooch

This vintage brooch by Bond Boyd is gold filled and has a modern locking c pin closure. The brooch is shaped like a trillium flower with 3 brushed metals and smooth, shiny pollen center. The back is stamped "Bond Boyd GF". There is general wear throughout and some minor tone loss on the edges. The marks on the back side are easy to see because of the smoothness of the metal, but the textures on the front help disguise any marks. The base metal under the gold fill might be sterling silver, but while I can't confirm it, it's worth mentioning. Dimensions: 67x54mm Weight: 11.48g
