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 0.7mm and they are available in 42 different colours. 5328 is also available in 4mm, 5mm, 6mm & 8mm.
