Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a 10 x 5 mm marquise diamond, casting a slender, luminous silhouette that gracefully extends the hand. This halo setting in 14K white gold frames the center stone with a delicate circle of pavé diamonds, enhancing its tapered drama without adding bulk.

Crafted with a low-profile mounting, the ring sits close to the finger, designed for everyday wear with a comfort-fit band that balances presence and ease. Each facet is polished and inspected in our Williamsburg studio, ensuring the setting secures the diamond while maintaining a sleek, refined line.

Our lab-grown diamond offers a clarity and brilliance equal to mined stones, with a smaller environmental footprint—an ethical choice made without compromise.

The elongated marquise shape naturally complements slender fingers and pairs well with stackable bands or a wedding ring, thanks to its streamlined silhouette and modest height. Its design is glove-friendly and unobtrusive, ideal for those who favor subtle sophistication.

Should you need resizing, we accommodate adjustments with care to preserve the ring’s integrity and comfort.
