Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This semi-set halo engagement ring foundation in 14K white gold offers a low-profile setting designed for everyday grace and ease.

Crafted with precision in Williamsburg, the band’s smooth comfort fit and secure prong structure ensure the stone you select will sit confidently close to the hand, minimizing snagging while maximizing sparkle. The halo setting frames the marquise shape, enhancing its natural brilliance without adding bulk.

Each piece reflects a commitment to sustainability through lab-grown diamonds, marrying ethical clarity with refined craftsmanship. The 12 x 6 mm marquise shape lends an elegant elongation, flattering a variety of hand sizes and complementing slender or wider fingers alike.

Ideal for those who appreciate a sleek profile that layers effortlessly with other bands or stands alone with quiet sophistication. Resizing is available to ensure a tailored fit, and our Brooklyn studio welcomes you to explore custom options or complete your ring with a center stone of your choice.
