Vintage Gold Tone Filigree Brooch with Black and Green Stones

Found this cool vintage-style brooch. It's got a gold-tone metal finish with a big dark stone in the middle and some smaller green and black accents around the edges. It has that classic filigree look, definitely feels like an older piece. Good for pinning on a jacket or a scarf if you're into that retro vibe. Not sure of the exact age but it's in decent shape.
