Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points 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 diamond’s vintage-inspired shape.

Each band is hand-forged in our Williamsburg studio, where the rose gold is carefully polished to a soft sheen that feels smooth against the skin. The low-profile setting ensures the ring sits comfortably for daily wear, while the three-stone design balances sparkle with understated elegance. The mounting awaits your choice of a 6 x 3.5 mm marquise center, ready to be paired with side stones that enhance its architectural charm.

Crafted with lab-grown diamonds, this piece reflects a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Its slender band and modest height make it ideal for those who appreciate a ring that layers effortlessly with wedding bands or stackable styles. The rose gold’s gentle warmth suits a variety of skin tones, while the marquise shape elongates the finger for a refined silhouette.

Should you need resizing or prefer a custom side stone arrangement, our Brooklyn studio offers personalized consultations to ensure the ring fits your vision and lifestyle.
