Lab-Grown Diamond Engagement Ring

Light catches the elongated curve of a marquise diamond, its pointed ends tracing a delicate silhouette that seems to stretch the hand with quiet elegance. This three-stone semi-set engagement ring in warm 14K rose gold frames a 9 x 4.5 mm marquise center, ready to cradle your chosen gem with slender prongs that balance security and grace.

Each band is hand-finished in our Williamsburg studio, polished to a soft glow that complements the rose’s gentle blush. The low-profile setting ensures the ring sits comfortably for daily wear, while the three-stone design offers a subtle narrative of past, present, and future.

Crafted exclusively for lab-grown diamonds, this piece reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its slender silhouette suits hands that appreciate refined geometry and pairs beautifully with stacking bands or a simple wedding ring. The comfort fit band allows for effortless wear, even beneath gloves or during busy days.

Should you need resizing, our in-studio experts handle adjustments with care, ensuring your ring fits as naturally as a second skin.
