Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 6 x 6 mm cushion diamond, its rounded corners offering a quiet glow that balances vintage warmth with modern clarity. This semi-set three-stone ring foundation in 10K rose gold frames your chosen center stone with subtle elegance, the warm blush of the metal enhancing the gem’s soft sparkle.

Crafted with a low-profile setting, the band’s smooth finish and delicate prongs ensure daily comfort and ease of wear, while the three-stone layout adds architectural balance without excess. Each piece is meticulously hand-finished in our Williamsburg studio, inspected for precision and durability.

Our commitment to lab-grown diamonds means your ring carries a lighter environmental footprint, reflecting a thoughtful approach to ethical jewelry.

Designed for those who appreciate refined minimalism, this ring’s slender band and modest height make it ideal for stacking or wearing alone, complementing a variety of hand shapes and sizes with understated confidence.
