Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender, luminous shadow across the hand. This three-stone engagement ring balances architectural grace with intimate sparkle, the 12 x 6 mm marquise center flanked by two delicately tapered accents.

Crafted in cool platinum, the ring’s low-profile setting hugs the finger with a comfort fit that invites daily wear. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the diamonds sit secure yet light, allowing their facets to dance freely in natural light.

Our commitment to sustainability is reflected in the lab-grown clarity of the stones, offering brilliance without compromise. This ring’s slender silhouette suits those who appreciate refined geometry and a subtle elongation of the hand, pairing effortlessly with stackable bands or worn solo.

Resizing is handled with care in-house, preserving the integrity of the setting and the smoothness of the band. Typical lead times align with our bespoke process, allowing for thoughtful customization without rush.
