Swarovski 4mm bicone Peacock Feather Mix contains: Metallic Blue 2X, Capri Blue, Emerald, Erinite, and Crystal Copper. Set your designs a cut above the rest with the new and revolutionary Xilion facets of Swarovski (art. 5328) bicones. Swarovski is giving their classic bicone (art. 5301) a face lift. The Xilion facets are copyright protected and unique only to Swarovski Crystal Beads. The copyright protected facets of the new Xilion bicone ensure that your genuine Swarovski design will be more easily distinguished from designs using inferior crystals! Perfect cuts and alternating large and small facets of the Xilion bicone result in more intense light reflection, than the 5301 bicone, and give the Xilion bicone an incomparable brilliance. The increased number of facets improve the appearance of the crystal, while the rounder center line improves overall wearability of the product.
