Three vintage brooches signed Giovanni

These are three beautiful vintage brooches signed Giovanni from my grandmothers collection from the 50s through 80s. They are in very good vintage condition. The one gold tone leaf brooch has some natural wear from age but the other two have little wear. The big one features two very detailed roses with leaves and stem. The smallest one is a silver tone leaf design. And the other is a gold tone leaf design. Smoke free home. Enjoy!💍
