Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set engagement ring in 10K white gold offers a sleek foundation for a 10 x 5 mm marquise center, designed with delicate accent stones that enhance its refined silhouette without overpowering.

Crafted in Williamsburg, the band features a low-profile setting that sits close to the skin, minimizing snagging and maximizing comfort for everyday wear. The white gold is hand-finished to a smooth, satiny touch, ensuring a gentle feel against the hand while maintaining structural integrity for daily life.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to ethical sourcing and sustainable practices without compromising on radiance.

This ring suits those who appreciate architectural elegance paired with practical design—its slender shape complements longer fingers and pairs effortlessly with stackable bands or wedding bands. The semi-set style invites you to choose a center stone that matches your vision, making it a personal and meaningful starting point.

Resizing is available to ensure a precise fit, and the studio’s Brooklyn-based artisans oversee every step from design to final polish, typically within a few weeks.
