Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light across the hand. This three-stone semi-set engagement ring in 18K rose gold frames a 10 x 5 mm marquise center, its pointed ends drawing the eye with subtle drama and refined elegance.

Each band is hand-shaped and polished in our Williamsburg studio, the warm rose gold softly curving to cradle the stones with a low-profile setting that rests comfortably for daily wear. The three-stone arrangement balances classic romance with modern craftsmanship, allowing you to select a center diamond that reflects your unique story.

Our commitment to sustainability shines through the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint. The gentle warmth of rose gold complements the marquise’s tapered form, making this ring an ideal choice for those who appreciate graceful geometry and a refined silhouette.

Designed for ease, the low-profile setting slips smoothly under gloves and stacks effortlessly alongside wedding bands or delicate bracelets. The semi-set format invites personalization, with expert resizing and care guidance available to ensure a perfect fit.
