Group of 7 PAIRS of old store stock 1970s to 1980s vintage blown glass enameled Murano bead stud earrings, pierced post with butterfly backs. They have a pretty multi color mix of red, yellow and black colors. Each earring is showy and noticeable at 9mm to 10mm size. They have silverplated posts with stainless butterfly backs. Any glue marks you see on the backs in the enlarged photos are not visible when the earrings are worn. Unknown if they are drilled but they do have back covers on the beads that are glued and secure. Never used and in like new condition. They are from the estate of a mid century jewelry store. Store in operation from 1960s to 2005 and these were stored in basement for decades. A lovely group of good sized vintage Murano glass earrings for you or for resale!
