These Czechoslovakian glass hearts were hand-made in molds during the 1980s and early 90s. Each heart is a deep purple, but light enough to be transparent. Each bead can accommodate up to a 0.5 mm cord. These beads are 12 mm from top to bottom and 11 mm across at the widest point. They are 4 mm thick. The hole is in the center of the top and this bead hangs like a charm. On a cord it would be sideways, so you would need to use a jump ring on a necklace or bracelet. They would hang beautifully on the end of an earring or as a charm. Price is for 10 beads.
