Preciosa® MC (machine cut) round stones are wholly machine cut, which ensures a precise cut and perfect sparkle of each stone. Bottom side of these original PRECIOSA cut stones is finished with a layer of simili that ensures impeccable shine and optimal optical properties of the PRECIOSA stones and does not contain any heavy metals or other harmful substances. You will find the procedure for the use of Glueing Stones in our manual. All PRECIOSA round stones are suitable for bezeling with seed beads or gluing into jewellery settings designed for specific stone shapes and sizes. The range contains by far the most popular round stone shape, PRECIOSA MC Rivoli MAXIMA, which is an alternative to the SWAROVSKI 1122 Rivoli stones. Next, PRECIOSA MC Chaton MAXIMA shape, which is an alternative to the SWAROVSKI 1028 XILION Chaton and SWAROVSKI 1088 XIRIUS Chaton products.
