Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated points of a marquise diamond, it casts a slender, dramatic silhouette that naturally draws the eye along the finger. This semi-set halo engagement ring in 18K white gold frames a 10 x 5 mm marquise center with a delicate circle of pavé stones, enhancing its brilliance without adding bulk.

Crafted in Williamsburg, the band is designed for everyday wear with a low-profile setting that sits close to the finger, reducing snagging while maintaining sparkle. The smooth comfort-fit shank balances durability with a refined touch, finished by hand to a subtle satin sheen that complements the diamond’s sharp geometry.

Each lab-grown diamond is selected for clarity and ethical provenance, reflecting a commitment to sustainability without compromising radiance. The halo setting amplifies the marquise’s signature tapered drama, making it a striking choice for those who appreciate architectural elegance paired with modern sensibility.

Ideal for slender to medium-width fingers, this ring layers effortlessly with wedding bands or stackable styles, thanks to its streamlined profile. Resizing is available to ensure a precise fit, with lead times tailored to your custom design experience in our Brooklyn studio.
