Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch the fingers with quiet elegance. This three-stone semi-set ring features a 6 x 3 mm marquise center, poised between two delicately crafted side stones, all framed in warm 10K yellow gold.

Each band is hand-shaped in our Williamsburg studio, with a low-profile setting that rests comfortably against the skin, designed for everyday wear without catching. The artisan finish reveals subtle hammer marks and polished edges, a tactile reminder of the human hand behind every curve.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both the environment and your values. This ring’s slender silhouette suits those who appreciate refined geometry and a graceful elongation of the hand, pairing seamlessly with stacking bands or worn solo.

Should you need a custom fit, resizing is handled expertly in-house to maintain the integrity of the setting and comfort fit. Lead times vary but we keep you informed throughout the process.
