Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette across the hand. This semi-set solitaire invites you to select a center stone that echoes that distinctive, tapered drama—measuring 12 by 6 millimeters for a striking presence.

Crafted from warm 10K yellow gold, the band is shaped with subtle tapering to complement the marquise’s architectural form. Its low-profile setting ensures the ring sits close to the finger, offering daily comfort without sacrificing elegance. Each piece is meticulously finished by hand in our Williamsburg studio, where artisan techniques meet modern precision.

Our commitment to sustainability shines through the exclusive use of lab-grown diamonds, chosen for their clarity and ethical origin. This ring’s design suits those who appreciate a bold yet refined statement, especially flattering on slender fingers or when paired with delicate stacking bands.

Because the center stone is sold separately, you have the freedom to select a marquise diamond that matches your vision and budget. Resizing is available to ensure a perfect fit, crafted with the same care as the ring itself.
