Three Vintage Clip-on Earrings: Shell with pearl, Black flower & Hummingbirds

These belonged to my mother-in-law, a very classic and elegant person. She never pierced her ears and these were from her travels to Hawaii, Europe and Mexico. Very fun! In EUC- clipping mechanism works. The black flower & shell/pearls are screw-in style (can Adjust); the hummingbird is a silver clip-on. Great as a gift or dress up for a young person with non-pierced ears? From a non-smoking household!
