Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, confident shadow across the hand. This semi-set engagement ring invites you to choose your own 8 x 4 mm center stone, framed by delicate accent diamonds that emphasize clarity and structure without excess.

Crafted in warm 14K rose gold, the band is polished to a soft glow that complements the sharp geometry of the marquise shape. The low-profile setting ensures the ring sits comfortably for daily wear, while the subtle accents add a refined sparkle that balances modern minimalism with architectural precision.

Each piece is finished by hand in our Williamsburg studio, where expert jewelers inspect every detail to meet exacting standards. The lab-grown diamond option offers a clear, sustainable choice—minimizing environmental impact without compromising brilliance.

This ring suits those who appreciate clean lines and confident design, especially flattering on slender fingers where the marquise shape elongates the hand. Its comfort fit and modest profile make it ideal for stacking or wearing solo, adapting seamlessly to everyday life.

Resizing is available to ensure a perfect fit, with typical lead times reflecting our commitment to careful craftsmanship.
