Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette that seems to stretch beyond the finger. This semi-set halo engagement ring foundation in 10K yellow gold invites your choice of a 9 x 4.5 mm marquise center, framed by a delicate halo that amplifies its sculptural elegance.

Crafted in our Williamsburg studio, the band is hand-finished to a smooth comfort fit, designed for daily wear without catching or discomfort. The low-profile setting balances presence with practicality, allowing the halo to enhance the diamond’s brilliance while maintaining a refined silhouette.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and sparkle with a smaller environmental footprint.

This ring suits those who appreciate architectural grace and vintage-inspired detail, especially flattering on slender fingers or when stacked with slim bands. Its modest height fits comfortably under gloves or sleeves, making it a versatile choice for everyday life.

Should you need resizing, our in-house artisans ensure a precise adjustment without compromising the ring’s integrity or finish.
