Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every movement, its tapered points lending a quiet drama to your hand. This semi-set halo engagement ring in 18K white gold frames a 9 x 4.5 mm marquise center, designed to balance presence with everyday ease.

Crafted with a low-profile halo setting, the ring offers a secure embrace for your chosen stone while maintaining a sleek silhouette that slips comfortably beneath gloves or sleeves. The polished 18K white gold band is finished by hand in our Williamsburg studio, ensuring a smooth comfort fit that wears effortlessly from morning coffee to evening plans.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to ethical sourcing and sustainability without compromise on sparkle.

Ideal for those who appreciate architectural elegance paired with practical design, this halo mounting complements the marquise shape’s elongating effect, flattering slender fingers and stacking beautifully with other bands.
