Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This solitaire semi-set ring in 14K yellow gold offers a refined foundation for a 7 x 3.5 mm marquise center, designed to showcase the stone’s tapered elegance without distraction.

Crafted with a low-profile setting, the band sits close to the finger, minimizing snagging while ensuring comfort for everyday wear. The warm glow of 14K yellow gold is hand-finished in Williamsburg, its smooth surface polished to a subtle sheen that complements the diamond’s sharp geometry.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry without compromise. This semi-set allows you to choose a center stone that fits your vision, supported by a secure, expertly engineered mounting.

The slender band and modest height suit those seeking a ring that layers effortlessly with wedding bands or stacks with other favorites. Its streamlined profile works well for active hands and fits comfortably under gloves or sleeves.

Resizing is available to ensure a precise fit, and our Brooklyn studio offers personalized consultations to guide your choice and care.
