VTG GUC Lot of 3 Pair Clip-on Earrings

Very nice condition for the age. These were my grandmother's and date from the 50s and 60s. First pair has black center with rhinestone frames. This pair shows the most wear. Center is matte black and these have always looked this way in the 40 years I've seen them. No manufacturer's markings. Second pair is fun blue and green beads. Marked Germany. Great condition. Third pair is stunning crystal clusters from Germany. Not marked. These are really gorgeous in person. All clasps work.
