Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a delicate shadow that dances with every movement. This three-stone semi-set engagement ring in warm 14K rose gold frames a 12 x 6 mm marquise center, its tapered silhouette evoking quiet drama and refined elegance.

Each band is hand-shaped and polished in our Williamsburg studio, designed with a low-profile setting that sits close to the finger for everyday comfort. The three-stone layout balances presence with grace, allowing the marquise to elongate the hand while side stones add subtle brilliance without bulk.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and sustainability, marrying beauty with conscience.

Its gentle curve and moderate width make it ideal for those who appreciate a romantic statement that layers effortlessly with wedding bands or stackable rings. The rose gold’s soft glow complements a variety of skin tones, enhancing the ring’s poetic warmth.

Should you need resizing, our in-house artisans ensure a precise fit without compromising the ring’s delicate structure.
