Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set solitaire invites you to choose a center stone that embodies your story, framed by the warm glow of 18K rose gold.

Crafted in Williamsburg, the slender band curves gently, offering a low-profile setting that rests comfortably against the finger. The rose gold’s subtle blush complements the marquise shape’s tapered points, enhancing its graceful drama without overwhelming daily wear. Each piece is meticulously finished by hand, ensuring smooth edges and a refined polish that catches light softly.

Our commitment to sustainability is reflected in the choice of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate a blend of classic romance and modern craftsmanship, especially fingers that favor elongated shapes or a slender silhouette. Its comfort fit and modest height make it ideal for stacking or wearing solo.

Should you wish to adjust the band size, resizing is available with care to preserve the integrity of the rose gold finish. Typical lead times for custom center stones and final assembly are communicated clearly to ensure a seamless experience.
