Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, graceful shadow across the hand. This semi-set solitaire ring features an 8 x 4 mm marquise center, chosen for its elegant taper and subtle elongation that visually lengthens the finger.

Crafted from warm 14K yellow gold, the mounting is designed with a low-profile setting that sits close to the skin, ensuring comfort for everyday wear. The band’s smooth finish and balanced weight provide a secure yet lightweight feel, ideal for those who prefer a refined silhouette without bulk.

Each ring is meticulously finished in our Williamsburg studio, where precision meets quiet durability. The semi-set design invites you to select a lab-grown diamond of your choice, reflecting our commitment to ethical sourcing and sustainable luxury.

Its slender shape and modest height make this ring well-suited for stacking or pairing with a wedding band, while the comfort fit band ensures ease of wear throughout daily life. The narrow marquise shape complements slender or average finger sizes, adding a touch of architectural elegance without overwhelming the hand.

Should you need resizing, our in-house artisans handle adjustments with care, maintaining the integrity of the setting and metalwork. Typical lead times accommodate custom stone selection and finishing.
