The Xirius Sew-on Stone is an upgraded version of the popular Xilion Sew-on Stone, and it features Swarovski's most brilliant innovation, Xirius. Named after the galaxy's brightest star, Xirius is as useful as it is radiant. With enhanced faceting that gives incredible light refraction, it can be used for decorative pieces, jewelry, embroidery, and more. Thanks to its perfect diameter and hole with rounded edges, the Xirius Sew-on Stone is particularly easy to apply. The balanced ratio of base-to-table size has been expertly calculated to achieve optimum levels of brilliance, as well as ease of application via hand-sewing or machine.
