Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise diamond, its tapered points drawing the eye along a delicate arc of platinum. This three-stone engagement ring balances architectural drama with subtlety, the center stone measuring 6 by 3.5 millimeters, flanked by two smaller companions that enhance its graceful silhouette.

Each platinum band is hand-forged in our Williamsburg studio, polished to a satin finish that feels smooth against the skin. The low-profile setting ensures the ring sits comfortably beneath gloves or daily wear, while the secure prongs cradle the marquise with precision, protecting its delicate points without sacrificing brilliance.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and sparkle without compromise.

Its slender shape and balanced weight make it ideal for those who appreciate a statement piece that remains refined and wearable—whether worn alone or paired with a stack of complementary bands.

Resizing is available to ensure a perfect fit, with careful attention to maintaining the ring’s structural integrity and finish.
