Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as a marquise diamond, measuring 7 by 3.5 millimeters, catches the light with its tapered brilliance. This semi-set halo engagement ring in 18K rose gold offers a delicate balance between presence and practicality, designed to sit low against the hand for everyday comfort.

Crafted in Williamsburg, the rose gold band is meticulously finished to a smooth, comfort-fit profile, ensuring it slips on easily and wears effortlessly alongside other rings. The halo setting, ready to embrace your chosen marquise center stone, enhances the diamond’s signature pointed shape without adding bulk, maintaining a sleek silhouette.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, reducing environmental impact while delivering exceptional clarity and sparkle. The semi-set design invites you to select a center stone that resonates personally, making this ring uniquely yours.

Ideal for those who appreciate refined geometry and a low-profile setting, this ring complements slender fingers and fits comfortably under gloves or daily wear. Its streamlined form also pairs well with stacking bands for a personalized look.
