The SWAROVSKI ELEMENTS style 5301 faceted bicones are being replaced with the innovative XILION cut, which features an increased number of alternating large and small facets. Now known as the 5328 XILION cut bicone, the new design creates higher brilliance with 12 meticulously-cut facets. This patented cut is bursting with captivating brilliance and will provide you with gorgeous results! Due to its small size, the intricate 5328 XILION cut cannot be manufactured using Swarovski's current crystal cutting technology on the 2.5mm bicones. For this reason, Swarovski will continue to promote the very popular existing 5301 faceted bicone using the new 5328 article number.
