Jewelry, one of the most ancient of arts, has evolved to incorporate brilliant new materials and processes, thanks in part to the creativity of Roberto Demeglio. In addition to being an award-winning designer of diamond jewelry, Demeglio holds patents for innovations that set his collections apart, like the internal flexibility that allows his prized diamond-encrusted bracelets to slip on and off with ease. Fans of Roberto Demeglio jewelry include Oprah, Shakira, and Alicia Keys.
