These vintage glass hearts were made in Czechoslovakia in molds during the 1980s. The heart is 8 mm from hole to hole and 8 mm wide at the widest point. The bead channel is small and will accommodate up to a 0.5 mm string. The heart is a translucent sapphire blue on one side and then a blue AB on the other. The translucent side has a bit of an acid wash finish. Price is for 10 beads.
