Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring in warm 18K rose gold offers a refined foundation for a 9 x 4.5 mm marquise center stone, emphasizing sleek elegance without excess height.

Crafted with a low-profile setting, the band’s gentle curve and secure prongs ensure daily comfort and durability. The rose gold’s subtle blush complements the diamond’s fiery facets, while the smooth finish reflects meticulous hand polishing and quality inspection in our Williamsburg studio.

Each lab-grown diamond is chosen for its clarity and brilliance, embodying a sustainable approach to fine jewelry without compromise. The slender silhouette suits hands seeking a graceful, elongating effect and pairs effortlessly with stacking bands or wedding rings.

Resizing is available to ensure a precise fit, and the semi-set design invites you to select a center stone that resonates personally, with expert guidance from our Brooklyn team. Whether worn daily or reserved for special moments, this ring balances technical assurance with understated beauty.
