Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set solitaire invites you to select a 10 x 5 mm marquise stone, whose tapered points and graceful curves evoke a quiet drama, perfect for a hand that appreciates subtle distinction.

Crafted in warm 14K rose gold, the mounting balances delicate romance with structural integrity. The slender prongs cradle the stone securely while maintaining a low profile, ideal for everyday wear without catching or discomfort. Each ring is meticulously finished by hand in our Williamsburg studio, ensuring smooth edges and a comfort fit that feels like a second skin.

Our commitment to ethical jewelry shines through the choice of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

This solitaire suits those who favor refined elegance and a ring that layers effortlessly with wedding bands or stackable accents. Its streamlined shape complements slender fingers and adapts well to glove wear, making it a versatile companion from morning coffee to evening walks along the East River.

Should you wish to adjust the fit, resizing is straightforward and handled with care by our in-house artisans.
