Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set halo ring foundation in warm 18K yellow gold invites your choice of a 7 x 3.5 mm marquise center stone, ready to be embraced by a delicate halo that amplifies its vintage-inspired drama.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that balances wearability and elegance. The low-profile setting ensures the ring sits close to the finger, making it ideal for daily wear and effortless stacking with other bands. Each prong is meticulously finished to secure the stone while maintaining a refined silhouette.

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

This design suits those who appreciate architectural lines softened by artisan detail—perfect for hands that favor elongated shapes and a ring that transitions seamlessly from studio to street.

Should you need resizing, our Brooklyn workshop provides precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
