Vintage 1960s Bird Brooches Set: Gold Tone Enamel Rhinestone Pins

Again, going through my vintage brooches and decided to put out some nature lovers' pieces. Why buy one when you can get three?? These are all high-quality pieces made of gold toned metal, enamel and rhinestones. They are not marked but a lot of them were not, the roll over clasps all work fine, the oldest one is missing a rhinestone eye but easily fixed. The largest one is absolutely beautiful, and I am sure it has a history from someone making it, did not research it. Great gift for our lovely vintage jewelry lover also.
