Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light as you move—its elongated, tapered silhouette lending a quiet confidence to your hand. This semi-set engagement ring foundation in 18K white gold awaits your choice of an 8 x 4 mm marquise center, framed by delicate accent settings that emphasize clarity and refined structure.

Crafted with precision in our Williamsburg studio, the band’s smooth, low-profile design ensures comfortable daily wear while maintaining a modern-minimal aesthetic. Each piece is hand-finished and carefully inspected to meet exacting standards, balancing durability with elegance.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering exceptional clarity and brilliance with a smaller environmental footprint.

This mounting suits those who appreciate architectural form and understated sophistication, pairing effortlessly with stackable bands or standing alone as a statement of intent. Its slender profile fits comfortably beneath gloves and complements a variety of hand shapes.

Should you need resizing, our in-studio experts handle adjustments with care, ensuring your ring fits perfectly without compromising its sleek lines.
