Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a quiet confidence that draws the eye along the finger. This semi-set engagement ring foundation in 10K white gold offers a sleek, modern-minimal frame designed to showcase a 7 x 3.5 mm marquise center stone, accented delicately to enhance its architectural clarity.

Crafted with precision in our Williamsburg studio, the band features a low-profile setting that balances presence with everyday comfort, its smooth finish inviting daily wear without catching. The accents are thoughtfully placed to complement the marquise’s tapered points, adding dimension without distraction.

Each lab-grown diamond we work with reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional clarity and brilliance.

Ideal for those who appreciate structured elegance and a refined silhouette, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding band designed for close fit.

Should you wish to adjust the band size or explore custom accent arrangements, our Brooklyn studio offers personalized consultations to ensure your ring fits your lifestyle perfectly.
