Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that seems to dance with every movement of the hand. This semi-set solitaire invites you to select the perfect 5 x 3 mm center stone, its pointed ends lending a subtle drama and graceful elongation to the finger.

Crafted in 14K white gold, the mounting features a refined low-profile setting designed for everyday wear. The slender prongs cradle the stone securely while maintaining an airy lightness, and the smooth band offers a comfortable fit that slips easily beneath gloves or alongside stackable rings.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every curve to ensure a seamless balance of strength and elegance. The choice of a lab-grown diamond center reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance.

This solitaire suits those who appreciate modern geometry with a romantic edge—ideal for hands that favor elongated shapes or for anyone seeking a ring that feels as natural as it looks striking. Resizing is available to ensure a perfect fit, and the semi-set design allows you to customize your center stone with confidence.
