Swarovski Round Stones are loose crystal elements. Most of them are pointed on the reverse side, making them easy to apply in either metal claw settings or pre-set cavities. The assortment features a wide variety of different cuts and sizes, the most innovative one being the XIRIUS Chaton and the smallest one being the XERO Chaton in size PP0. The science of the cut and the celebration of crystal as high art come together in the XIRIUS Chaton, Swarovski€™s most brilliant crystal element ever. Merging a gemstone-like cut with rich, varied color and Platinum Pro colored foiling for exceptional durability, XIRIUS takes crystal one step closer to the diamond.
