Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set halo engagement ring offers a 12 x 6 mm marquise center stone, ready to be paired with your choice of lab-grown diamond, framed by a delicate halo that enhances its fiery sparkle without adding bulk.

Crafted in 14K white gold, this mounting balances refined elegance with everyday practicality. The low-profile setting keeps the ring close to the hand, reducing snagging while maintaining a confident presence. Each curve is polished to a smooth finish, ensuring comfort for daily wear and compatibility with stacking bands or wedding rings.

Our commitment to sustainability is reflected in the use of ethically sourced lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

Designed for those who appreciate architectural grace and subtle drama, this ring suits slender to medium finger shapes, elongating the hand with its tapered form. The halo setting adds dimension while preserving a sleek silhouette that fits comfortably under gloves or sleeves.

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