Vintage Silver Tone Rose Bouquet Brooch

This vintage brooch is made of silver tone metal and has a modern locking c pin closure. The brooch features three roses in bloom, which appear to belong to the same plant. There are two petals that have a gold tone to them, and I'm unsure if the silver has come off or if the brooch was previously gold and all but those two spots have turned silver. There is some tone loss on the back near the pin closure and there is general wear throughout. Dimensions: 50x34mm Weight: 14.19g
