Vintage ruby and glitter mosaic stud earrings in a domed gumdrop stud style with a shiny glass-like appearance.  These are part of the 'Gumdrop Stud' line & it comes in loads of colors & sizes. Each measures about 11mm. 

Earrings are made with vintage lucite parts that were made in the US in the 1960's - early 80's. We hand-set them with surgical steel earring posts and they have sturdy surgical steel/acrylic backings on them as well. Light-weight & fun to wear.
