THESE EARRINGS HAVE THE MOST DELICATE AND REFINED APPEARANCE.  WHEN PRESENTED TO ME ABOUT 15-20 YEARS AGO, I WAS TOLD THAT THEY WERE MADE OF VENETIAN GLASS AND CRYSTAL.
SINCE I'M SELLING THEM, I WANTED TO BE CONFIDENT ABOUT THE MATERIALS.  I CHECKED YUMI JEWELRY'S WEB SITE AND THE ARTIST IS SELLING A SIMILAR STYLE NOW AND STATES THAT SHE USES VENETIAN GLASS AND CRYSTAL.
