The Tiffany setting is the most popular diamond solitaire ring setting consisting of six prongs that cradle and support the diamond. These prongs hold the diamond securely while enabling the maximum amount of light to enter the stone. The diamond will appear larger and more brilliant than with any other type of setting - a perfect choice for an engagement ring or eternity ring.
