Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set solitaire invites you to select a 7 x 3.5 mm lab-grown marquise, a shape known for its tapered drama and hand-flattering elongation.

Crafted in 14K yellow gold, the mounting features a low-profile setting designed for everyday wear. The slender prongs hold the stone securely while allowing light to flood the diamond’s facets, enhancing its brilliance without excess height. The band’s smooth finish and comfort fit ensure it sits close to the finger, ideal for stacking or solo wear.

Each piece is meticulously finished in our Williamsburg studio, where precision meets quiet durability. The ethical clarity of lab-grown diamonds complements the sustainable ethos behind every ring we create.

This solitaire suits those who appreciate refined geometry and a subtle statement, especially on slender to medium fingers. Its low profile makes it glove-friendly and unobtrusive for daily life.
