Sunlight catches the three perfectly matched round diamonds, each measuring 7.4 mm, casting a lively dance of brilliance across the warm 14K yellow gold band. This three-stone engagement ring balances presence with everyday grace, its low-profile setting crafted to sit comfortably against the skin without catching.

Hand-forged in our Williamsburg studio, the band is meticulously shaped and polished to a smooth comfort fit, ensuring it wears like a second skin. The prongs cradle each lab-grown diamond securely, allowing light to flood every facet and amplify the signature sparkle of the round cut—known for its classic fire and scintillation.

Each diamond is ethically cultivated, reflecting a commitment to sustainability without compromise on clarity or brilliance. The ring’s design suits those who appreciate artisan craftsmanship paired with a refined, wearable silhouette—ideal for stacking or solo wear, and glove-friendly for daily life.

Should you need a custom fit, resizing is handled expertly in-studio to maintain the ring’s integrity and finish. Typical lead times align with our bespoke process, ensuring every detail meets your vision.
