Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that draws the eye along the finger’s natural line. This semi-set solitaire ring offers a refined foundation in 18K white gold, designed to showcase a 10 x 5 mm marquise center stone of your choosing.

Crafted with a low-profile setting, the band sits close to the hand, balancing presence with everyday comfort. The smooth, polished shank ensures a secure yet unobtrusive fit, ideal for those who prefer subtle elegance without sacrificing durability. Each piece is meticulously finished and inspected in our Williamsburg studio to meet exacting standards.

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

The slender silhouette suits hands that appreciate architectural grace, and its streamlined design pairs effortlessly with stacking bands or a wedding band. Its low profile also makes it glove-friendly and practical for daily wear.

Should you need resizing, our in-house artisans handle adjustments with care to maintain the ring’s integrity and comfort fit.
