Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set engagement ring frame, crafted from warm 18K yellow gold, awaits a 12 x 6 mm marquise center stone to complete its refined profile.

The band’s low-profile setting ensures the ring sits close to the finger, minimizing snagging while offering a sleek, modern silhouette. Accents along the shank add subtle sparkle without overwhelming the diamond’s distinctive shape. Each curve and facet is carefully finished by hand in our Williamsburg studio, where precision meets comfort in every contour.

Choosing a lab-grown diamond here means embracing clarity and brilliance with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

Designed for daily wear, this mounting suits those who appreciate architectural elegance paired with practical comfort. Its streamlined form fits well alongside wedding bands or stackable rings, and the smooth interior promises a comfort fit that feels natural throughout the day.

Should you need resizing, our in-studio experts handle adjustments with care, ensuring your ring fits perfectly without disrupting the setting’s integrity.
