Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc that both sharpens and softens the hand’s natural lines. This semi-set halo engagement ring frames a 7 x 3.5 mm marquise stone, designed to amplify its signature pointed elegance with a circle of finely crafted pavé diamonds.

Forged from 10K white gold, the band carries a subtle sheen that complements the diamond’s icy fire without overwhelming it. The halo setting is meticulously hand-set in our Williamsburg studio, ensuring each tiny accent stone sits flush for a low-profile, comfortable wear that slips easily beneath gloves or alongside stackable bands.

Our commitment to sustainability is reflected in the choice of a lab-grown marquise diamond, offering clarity and brilliance with a lighter environmental footprint. This ring’s slender shank and secure prong setting suit those who appreciate refined geometry paired with everyday practicality.

Because this is a semi-set, the center stone can be selected to your exact preferences, allowing a personalized balance of size and sparkle. Resizing is available to ensure the ring fits seamlessly, crafted for daily life without compromise.
