Vintage Marcasite & Faux Pearl Leaf Brooch

This vintage brooch is made of silver tone metal and has a modern locking c pin closure. The brooch itself is shaped like a curved leaf and is dotted with small marcasite stones and larger faux pearls. The underside is stamped "PAT 2246389" (that's the closest I can get). There is some tone loss and loss of the faux pearl coating, but it is not noticeable among the marcasite sparkles. Dimensions: 58mm x 26mm Weight: 15.87g
