Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam across the hand. This solitaire semi-set invites you to select a 6 x 3.5 mm lab-grown marquise, its tapered points offering a striking balance of drama and elegance.

Crafted in warm 14K rose gold, the mounting features a low-profile setting designed for everyday wear. The slender prongs secure the stone while maintaining a sleek profile that slips comfortably beneath gloves and stacks seamlessly with other bands. Each ring is meticulously finished by hand in our Williamsburg studio, ensuring smooth edges and a comfort fit tailored to your lifestyle.

Our lab-grown diamonds reflect a commitment to ethical jewelry, offering clarity and brilliance without compromise. This approach reduces environmental impact while delivering the refined sparkle you expect.

Ideal for those who appreciate architectural grace with a modern touch, the marquise shape elongates the finger, making it a flattering choice for slender or average-sized hands. The solitaire design emphasizes the diamond’s unique form, perfect for a confident, understated statement.
