Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, confident sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring in 18K yellow gold offers a refined foundation, ready to showcase your chosen 6 x 3.5 mm marquise stone with subtle accent details that enhance its modern-minimal clarity and structure.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure everyday comfort without sacrificing presence. The warm glow of 18K yellow gold complements the marquise’s tapered drama, while the accents add a quiet architectural balance, all polished to a gentle sheen and inspected meticulously for lasting wear.

Each diamond is lab-grown, reflecting a commitment to ethical jewelry that honors both beauty and sustainability. The semi-set design invites personal choice, allowing you to select a center stone that resonates with your vision.

Ideal for those who appreciate clean lines and confident form, this ring fits comfortably under gloves and pairs effortlessly with stackable bands. Its slender shape flatters a variety of hand sizes, making it a versatile piece for daily wear.
