Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with a subtle, elegant drama. This three-stone semi-set engagement ring in 18K rose gold offers a warm, blush-hued frame that complements the stone’s vintage-inspired shape.

Each band is meticulously crafted in our Williamsburg studio, where the rose gold is hand-finished to a soft, satiny sheen. The low-profile setting ensures the ring sits comfortably for daily wear, while the three-stone design balances presence with refined ease. The mounting awaits your choice of a 9 x 4.5 mm marquise center, ready to be paired with side stones that enhance its architectural grace.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable practices, reflecting a modern approach to ethical jewelry.

Designed for those who appreciate artisan detail and a ring that feels as natural as it looks, this piece suits slender to medium fingers and layers beautifully with stackable bands or wedding rings. Its shape and setting keep it glove-friendly and unobtrusive without sacrificing character.
