Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender, luminous shadow that dances across the skin. This semi-set solitaire invites you to choose a center stone that embodies that graceful, tapered drama—6 by 3 millimeters of refined sparkle waiting to be framed.

Crafted in warm 14K yellow gold, the mounting balances delicate strength with everyday wearability. The slender band tapers gently, offering a low-profile silhouette that sits close to the finger, while the prongs cradle the stone securely without overwhelming its shape. Each piece is hand-finished in our Williamsburg studio, polished to a soft glow that complements the diamond’s sharp geometry.

Our commitment to lab-grown diamonds ensures clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

This solitaire suits those who appreciate subtle drama and refined lines—its narrow profile fits comfortably beneath gloves and pairs effortlessly with stacking bands. The semi-set design allows you to select a marquise stone that matches your vision, whether you prefer a delicate sparkle or a bold statement.
