Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident, architectural gleam. This semi-set engagement ring in 18K white gold offers a sleek foundation designed to showcase a 9 x 4.5 mm marquise center stone, framed by delicate accent details that enhance its modern-minimal appeal.

Crafted in Williamsburg, the band features a low-profile setting that sits close to the finger, balancing presence with everyday comfort. The polished white gold surface is meticulously finished to a smooth, reflective sheen, ensuring the ring feels as refined as it looks. Its structure supports secure prongs tailored to cradle the pointed ends of the marquise, marrying clarity with strength.

Each lab-grown diamond chosen for this setting reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity. The ring’s design suits those who appreciate clean lines and architectural form, especially flattering on slender fingers or when paired with stackable bands.

Resizing is available to ensure a precise fit, and the semi-set nature invites you to select a center stone that resonates personally, making the design uniquely yours. Whether visiting our Williamsburg studio or designing online, this ring offers a thoughtful balance of modern structure and timeless craftsmanship.
