SWAROVSKI ELEMENTS 8mm 5328 XILION bead. The XILION Bead is the most popular bead shape that we sell, it replaces the 5301 Bicone bead which Swarovski have transformed into the new patented 5328 shape: It features 50% more facets for extra brilliance and light refraction, a smoother equator for increased comfort during wearing and rounded hole edges?to protect stringing materials. The hole size is approximately 1.2mm, they are available in 33 different colours. 5328 is also available in 3mm, 4mm, 5mm & 6mm. These 8mm Swarovski crystal beads are incredibly versatile and work well in almost any project. They are fairly large so are prefect as focus beads in a project and for necklaces.
