Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set solitaire ring features a 6 x 3.5 mm marquise center, poised in an 18K white gold band designed for everyday grace.

Crafted with a low-profile setting, the mounting keeps the diamond close to the hand, minimizing snagging while maximizing comfort. The polished white gold shank is smoothly contoured for a comfort fit, making it an ideal choice for those who wear their engagement ring daily without interruption.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to ethical sourcing and sustainable practices. The semi-set design invites you to choose a center stone that resonates personally, ensuring a custom experience rooted in Brooklyn craftsmanship.

Its slender shape complements a variety of hand sizes and pairs effortlessly with stacking bands or wedding rings. The ring’s streamlined profile also fits comfortably under gloves or sleeves, supporting an active lifestyle without compromise.
