Vintage sapphire blue faceted rondelle

These glass rondelles are really lovely. The whole edge is faceted, and the color is a lovely, clear sapphire blue. The rondelle is 10 mm and is 2 mm thick. It would be a great accent bead for so many projects. The beads were made in Czechoslovakia during the 1950s in molds. Price is for 100 beads.
