Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident edge, poised to crown a halo of delicate brilliance. This semi-set engagement ring foundation in 10K white gold offers a modern-minimalist framework, where clean lines and precise angles frame the center stone’s architectural grace.

Crafted in Williamsburg, the band’s low-profile setting ensures a comfortable fit for daily wear, while the halo setting promises to amplify sparkle without overwhelming. Each curve is hand-finished to a smooth, tactile perfection, reflecting the studio’s commitment to refined craftsmanship and thoughtful design.

Our lab-grown diamonds bring clarity and sustainability together, offering an ethical alternative that honors both beauty and conscience. The 12 x 6 mm marquise shape naturally elongates the finger, ideal for those who appreciate a sleek, confident statement piece that pairs effortlessly with stacking bands or a wedding band.

Should you wish to adjust sizing, our in-studio experts provide seamless resizing to ensure your ring fits like a second skin. Whether you choose to visit us in Williamsburg or begin your custom journey online, this semi-set invites you to select the perfect marquise diamond to complete your vision.
