Vintage Silver Tone Rhinestone Brooch Pin ✨ Trumpet Trombone ?

Vintage Silver Tone Rhinestone Brooch Pin ✨ Trumpet ? Trombone ? Such a pretty vintage pin! Loaded with rhinestones. Center, along the top & bottom bars, and on the horn area as well. Unsure of metal, but it does attract our magnet. A little finish wear, but still loads of shine. Light yellowing behind the rhinestones with magnification. See the close-up photos. Sizing in photos. Don’t see any signature, unless we’re missing it. Lovely! BP173
