Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that naturally draws the eye along the length of the finger. This semi-set halo engagement ring in 18K yellow gold offers a refined foundation for a 12 x 6 mm marquise center, designed with a low-profile setting that balances presence with everyday comfort.

Crafted in Williamsburg, the band’s smooth finish and secure halo setting are engineered to minimize snagging while enhancing the diamond’s brilliance. The warm glow of 18K yellow gold complements the marquise’s tapered shape, creating a harmonious contrast that feels substantial yet unobtrusive. Each ring undergoes meticulous hand inspection to ensure durability and a comfort fit that suits daily wear.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint.

Ideal for those who appreciate architectural elegance paired with practical design, this ring’s slender profile and secure halo make it glove-friendly and stackable with other bands. The semi-set style invites you to select a center stone that matches your personal vision.
