Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set engagement ring offers a halo setting designed to amplify the stone’s graceful shape without adding bulk.

Crafted in warm 14K yellow gold, the band is polished to a smooth finish that feels weightless in daily wear. The low-profile halo setting balances brilliance with practicality, ensuring the ring slips comfortably beneath gloves or sleeves. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of fit and finish.

Our commitment to sustainability is reflected in the choice of a lab-grown marquise diamond, providing clarity and sparkle with a lighter environmental footprint.

Ideal for those who appreciate architectural elegance paired with everyday ease, this ring complements slender fingers and suits stacking with complementary bands. The semi-set design invites you to select a center stone that resonates personally, making the ring uniquely yours.
