Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring offers a 9 x 4.5 mm marquise center, designed to balance presence with everyday ease.

Crafted in 10K yellow gold, the band is shaped for comfort and low profile, allowing the stone to sit close to the hand without catching. Fine accent stones frame the setting, enhancing the diamond’s signature brilliance while maintaining a sleek, secure mount. Each ring is finished by hand in our Williamsburg studio, inspected for smooth edges and flawless fit.

Choosing a lab-grown diamond ensures clarity and sparkle with a smaller environmental footprint, reflecting a modern commitment to ethical jewelry.

The narrow marquise shape naturally elongates the finger, ideal for those seeking a refined yet distinctive look. Its low-profile setting pairs well with wedding bands or stackable rings, and the comfort fit band suits daily wear without compromise.

Resizing is available to ensure a precise fit, with typical lead times of 4–6 weeks from design approval.
