The round brilliant cut has been the world's most sought-after diamond shape for over a century, and for good reason. With 57 or 58 precisely angled facets engineered to maximize light return, a well-cut round brilliant doesn't just reflect light, it amplifies it. 

Platinum is the ideal setting for a diamond of this quality. Its naturally white luster requires no rhodium plating to maintain, so the metal's color never drifts over time. The four-prong head holds the stone securely while keeping as much of the girdle visible as possible, letting the diamond breathe and catch light from every angle. The band shows the warm, bright polish of a well-kept piece with only minor surface reflections consistent with light wear, nothing that affects the integrity or appearance of the setting.

A solitaire in platinum round brilliant is one of the most enduring choices in fine jewelry. It suits a first engagement, an anniversary upgrade, or a right-hand fashion ring worn alone or paired with a slim platinum band. Size 5 fits most ring fingers and can be sized by a skilled bench jeweler if needed. We acquired this piece through our estate buying program and have fully inspected it at our Boca Raton showroom.

Each piece is fully inspected and authenticated by Diamonds by Raymond Lee in Boca Raton.
