Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the skin. This semi-set halo ring invites you to choose a center stone that will stretch gracefully along the finger, its 8 x 4 mm shape evoking a quiet elegance with a hint of vintage allure.

Crafted from warm 10K yellow gold, the band is polished to a soft glow, its gentle curve designed for everyday wear. The halo setting frames the center stone with a delicate circle of smaller diamonds, enhancing brilliance without overwhelming the refined profile. Low-set prongs keep the ring close to the hand, making it comfortable beneath gloves or alongside stackable bands.

Each piece is finished and inspected in our Williamsburg studio, where precision meets subtle artistry. The choice of a lab-grown diamond ensures clarity and sparkle with a lighter environmental footprint, reflecting a commitment to ethical jewelry.

This ring suits those who appreciate a blend of classic form and modern sensibility—its slender shape elongates the finger, while the halo adds a whisper of radiance. Whether worn solo or paired, it balances presence with discretion.

Resizing is available to ensure a perfect fit, and the semi-set design means your chosen marquise diamond will be expertly mounted to harmonize with the setting’s proportions.
