Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with a quiet drama. This solitaire engagement ring, set in cool platinum, showcases a 12 by 6 mm marquise stone whose sharp geometry contrasts with the smooth, polished band.

Handcrafted in our Williamsburg studio, the ring features a low-profile setting that secures the diamond with slender prongs, allowing light to flood the facets while maintaining everyday wearability. The comfort-fit platinum band balances strength with a gentle curve beneath the finger, designed for seamless stacking or solo elegance.

Each lab-grown diamond is cultivated with precision, offering clarity and brilliance without the environmental cost of traditional mining. This ethical choice aligns with a commitment to sustainability embedded in every piece we create.

Ideal for those who appreciate architectural lines and a statement that feels both modern and personal, the marquise shape elongates the hand, lending a refined silhouette that complements slender or broader fingers alike.

Should you need a custom adjustment, resizing is available to ensure a perfect fit without compromising the ring’s integrity.
