Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set solitaire invites you to select a 7 x 5 mm oval center, known for its graceful elongation that visually lengthens the finger with quiet elegance.

Crafted in a fixed two-tone combination of 18k white and 18k white and platinum and 18k white and platinum, the band balances cool brilliance with structural strength. The six-prong setting secures the diamond with minimal metal intrusion, allowing light to flood the stone’s facets while maintaining a low-profile silhouette that slips comfortably beneath gloves or daily wear.

Each piece is meticulously finished in our Williamsburg studio, where hand polishing and rigorous inspection ensure a smooth comfort fit and refined edges. The fixed two-tone design offers subtle contrast—18k white and platinum prongs frame the diamond against a 18k white and 18k white and platinum shank—highlighting the stone’s clarity and shape with modern precision.

Our lab-grown diamonds provide a transparent origin and a smaller environmental footprint, aligning with a mindful approach to fine jewelry.

This ring suits those who appreciate architectural simplicity paired with a confident statement—ideal for stacking or as a singular focus. The low-profile setting complements slender to medium finger sizes, enhancing natural hand lines without overwhelming.
