I got the earrings with beautiful beads as a gift, they looked very nice. The second time i wore them, i changed the class bead, the stopper at the bottom must have come loose, the beads fell while i was at work. I recovered the glass beads, but lost the sterling silve stopper that screws at the bottom to hold the glass beads. I have one useless earring now, does the company sell stopper beads for these earrings? not too happy about design.
