Lab-Grown Diamond Engagement Ring

Soft light filters through 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 in warm 18K rose gold offers a subtle glow that complements the stone’s vintage-inspired silhouette.

Each band is meticulously crafted in our Williamsburg studio, where the rose gold is hand-finished to a smooth, comfort-fit profile that sits close to the finger without sacrificing presence. The three-stone setting balances classic elegance with artisanal precision, designed to showcase your chosen center stone alongside two side gems, enhancing brilliance without bulk.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, ensuring clarity and ethical provenance without compromise.

Ideal for those who appreciate a ring that feels as natural in daily wear as it does in moments of celebration, this setting’s low profile and refined edges make it glove-friendly and stackable with complementary bands.

Should you need resizing or prefer a custom side stone selection, our Brooklyn studio offers personalized consultations to tailor the ring to your vision.
