Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded facets of a 7 x 7 mm cushion-cut diamond, its gentle glow unfolding like a whispered promise. This three-stone engagement ring, crafted in warm 14K yellow gold, balances romantic presence with everyday grace.

Each diamond is carefully set to maximize light reflection while maintaining a low-profile silhouette that rests comfortably against the skin. The band’s subtle curve and polished finish speak to meticulous handcrafting, refined in our Williamsburg studio where every detail is inspected for lasting wearability.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both beauty and sustainability without compromise.

Designed for those who appreciate a ring that feels as natural as it looks, this piece suits a variety of hand shapes and is ideal for stacking alongside complementary bands or worn solo with quiet confidence.

Should you need a custom fit, resizing is available to ensure the ring feels as effortless as it appears.
