Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a striking, tapered brilliance that draws the eye along the finger. This semi-set solitaire ring foundation in 18K white gold offers a sleek, low-profile frame designed to showcase a 9 x 4.5 mm marquise center stone with architectural grace.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of polished white gold meets a subtle comfort fit that rests naturally against the skin. The setting’s prongs are shaped to cradle the stone securely while maintaining an airy openness that maximizes sparkle and daily wearability.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, ensuring clarity and brilliance without compromise to the environment.

This design suits those who appreciate a refined statement piece that balances bold geometry with understated elegance. Its slender profile pairs effortlessly with stacking bands or stands alone as a distinctive engagement ring. The semi-set nature invites you to select a marquise diamond that resonates personally, making the ring uniquely yours.

Should resizing be needed, our in-studio experts handle adjustments with precision to maintain the ring’s integrity and comfort.
