Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This three-stone semi-set ring in 18K rose gold offers a warm, subtle glow that complements the stone’s tapered drama.

Each band is hand-shaped and polished in our Williamsburg studio, the rose gold’s soft blush achieved through meticulous finishing that balances durability with everyday wear. The semi-set design invites you to select a 7 x 3.5 mm marquise center diamond, allowing personal choice while ensuring a secure, low-profile setting that sits comfortably against the finger.

Crafted with lab-grown diamonds, this ring reflects a commitment to sustainable luxury—minimizing environmental impact without compromising brilliance or clarity.

The slender band and three-stone layout suit those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable styles. Its modest height makes it glove-friendly and ideal for daily life without catching or snagging.

Should you need resizing, our in-house artisans handle adjustments with care to maintain the ring’s balance and finish.
