These are called" illusion Eyeglass Holders" The cord is invisible and when you have your glasses on you look like you are wearing a gorgeous pair of earrings. We discovered those in European Riviera, You might not be able to travel to European Riviera now but you can a have piece of it!! Enjoy
They are made of glass, synthetic and crystal beads accented with metallic glass beads. Colors are much more vibrant than in those pictures. You will definitely love them.
