Lab-Grown Diamond Engagement Ring

Soft light catches the gently rounded corners of a 9 x 9 mm cushion diamond, poised to become the heart of a three-stone engagement ring. This semi-set foundation invites your choice of center stone, framed by two delicately sculpted side settings crafted in warm 18K rose gold, seamlessly flowing into cool 18K white gold for a subtle contrast that enhances the ring’s quiet complexity.

Each band is meticulously hand-finished in our Williamsburg studio, with a low-profile setting designed for everyday wear and a comfort fit that feels like a second skin. The three-stone layout balances presence with grace, allowing the center diamond’s soft vintage glow to harmonize with the shimmer of its companions.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate artisan craftsmanship and desire a piece that layers beautifully with wedding bands or stackable rings, while its modest height ensures ease with gloves or daily tasks.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure a perfect fit without compromising design integrity.
