Unusual Crystal Fine Rocks Tube beads (Article 5951) from Swarovski's Spring/Summer 2019 Product Launch are similar to a pavé bead, but with even more sparkle. Swarovski has achieved highly-refined surface brilliance by coating a 15mm tube with double-pointed chatons in tiny size PP14, resulting in an innovative look. These 15mm Crystal Fine Rocks tube beads have no end caps, so you can mix them into sterling silver and karat gold jewelry, or with your favorite platings. Add your own (approximately 6mm diameter) bead caps or favorite spacer beads (6mm or larger) to protect and enhance the ends. Easy to string on sturdy cord 1mm and smaller, including leather and cotton cording.
