Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring invites you to select an 8 x 4 mm marquise stone, known for its tapered points and graceful, vintage-inspired profile.

Crafted from warm 10K yellow gold, the band is shaped with subtle artisan touches—smoothly polished and gently rounded for a comfort fit that feels effortless against the skin. The low-profile setting balances security with everyday wearability, designed to slip easily beneath gloves or stack alongside other bands without crowding.

Each piece is finished in our Williamsburg studio, where expert hands inspect every curve and prong, ensuring a refined, tactile experience that honors the craft behind the metalwork. The choice of a lab-grown diamond reflects a quiet commitment to ethical jewelry, reducing environmental impact while offering clarity and brilliance.

Ideal for those who appreciate a blend of classic form and modern responsibility, this ring suits slender to medium finger shapes, enhancing length with its architectural cut. Resizing is available to ensure a precise fit, crafted with care to maintain the band’s smooth silhouette.
