Lab-Grown Diamond Engagement Ring

Sunlight catches the marquise’s tapered points, casting a subtle sparkle that draws the eye along its elegant silhouette. This semi-set engagement ring frame is crafted from 18K yellow gold, designed to cradle a 6 x 3 mm marquise diamond with precision and grace.

The setting features delicate accent details that enhance the center stone’s elongated shape while maintaining a low profile for everyday comfort. Its streamlined band sits close to the finger, minimizing snagging and allowing for effortless stacking with other rings or wedding bands.

Each piece is meticulously finished in our Williamsburg studio, where expert hands ensure smooth edges and a secure fit. The choice of a lab-grown diamond aligns with a commitment to sustainable luxury, offering clarity and brilliance without compromise.

Ideal for those seeking a refined yet practical ring, this mounting suits slender to medium finger sizes and complements the marquise’s natural elongation, subtly enhancing the hand’s shape. The semi-set design invites you to select a center stone that reflects your personal story.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care recommendations to preserve the ring’s finish and comfort.
