The best setting for a 5-carat diamond ring is the one that best enhances and protects the diamond. All VRAI engagement ring settings are designed for any carat weight. But, depending on your lifestyle, we may recommend choosing a setting that offers enhanced protection. Bezel settings are considered the most secure setting as they cover the entire diamond, including its points, corners, and edges. A 6 or 8 Prong setting, as well as a Halo setting, will also offer additional protection for your 5-carat diamond.
