These 4mm light sapphire luster iris beads will accent your designs with a cool blue shade. Each round glass bead has a transparent iridescent coating that adds hints of other colors to the mix. You can try these beads in a fancy design next to Swarovski crystal beads or create something more casual by incorporating brass links. These beads come in a pack of 100. Czech glass druks are pressed-glass beads made in the Czech Republic. These beads are still made in small quantities by hand. Be sure to explore the rest of our Czech druk beads for other colors, sizes and finishes.
