Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch the fingers with quiet elegance. This semi-set halo ring foundation in 10K yellow gold invites your choice of a 6 x 3 mm lab-grown marquise center, framed by a delicate halo that amplifies its light and presence.

Crafted in our Williamsburg studio, the band is hand-finished to a smooth comfort fit, designed for daily wear without catching or discomfort. The halo setting balances sparkle with subtlety, keeping the profile low enough to slip easily beneath gloves or stack alongside other bands.

Each lab-grown diamond is selected for clarity and brilliance, reflecting our commitment to sustainable, ethical jewelry that honors both craft and conscience.

This ring suits those who appreciate architectural grace with a vintage whisper—elongated shapes that flatter slender fingers and bring a refined statement to the hand.

Should you need resizing, our in-studio artisans ensure a precise adjustment without compromising the setting’s integrity.
