Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, poised to catch light from every angle, lends a subtle drama to this semi-set engagement ring foundation. Crafted in warm 14K yellow gold, the mounting balances a refined low profile with secure prong settings designed to cradle a 6 x 3.5 mm center stone without excess height.

Each band is hand-finished in our Williamsburg studio, polished to a smooth comfort fit that wears effortlessly day to day. The accent details along the shank add a whisper of texture while maintaining a streamlined shape that slips easily beneath gloves or rings stacked alongside.

Our commitment to lab-grown diamonds ensures clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry. This semi-set allows you to select a marquise cut diamond that suits your vision, supported by a setting engineered for durability and everyday grace.

Ideal for those who appreciate architectural elegance paired with practical design, this ring foundation complements slender to medium finger sizes and adapts well to custom sizing. Resizing is available to ensure a precise fit without compromising the integrity of the setting.
