Blackberry Screwback Earrings w/ Black Glass Beads

My husband says these look like blackberries, but I wouldn't advise letting anyone nibble them off your ears! Large clusters of round black glass beads individually attached to a screw type backing. No marks that we can find as to maker or place of origin, but I would imagine the beads are gablonz or bohemian. Diameter is approx. 3/4 inch. Simply stunning.

Good pre-owned vintage condition. Please note: Our photos are taken with a high definition closeup lens. The pictures you see are the equivalent of looking at the piece through a strong magnifying glass and may show flaws that are not apparent to the naked eye. We do not deep clean vintage jewelry and some items may have age appropriate patina or tarnish, especially in the deep recesses. Please examine all photographs as they are your best indicator as to appearance and condition.
