Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 12 x 6 mm marquise diamond, it draws the eye along its tapered points, creating a striking sense of movement and grace. This three-stone semi-set ring in 14K white gold offers a refined foundation, designed to showcase your chosen center stone with a secure, low-profile setting that sits comfortably for everyday wear.

Crafted in Williamsburg, Brooklyn, the band is meticulously shaped for a smooth comfort fit, ensuring it complements the hand without catching or bulk. The three-stone arrangement balances visual drama with practical elegance, allowing for effortless stacking or solo wear. Each piece is hand-finished and inspected to meet exacting standards of polish and durability.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and brilliance with a reduced environmental footprint.

Ideal for those who appreciate architectural lines and a ring that integrates seamlessly into daily life, this semi-set invites you to select a marquise diamond that resonates with your personal story. The low profile and balanced weight make it glove-friendly and suitable for active hands.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive care to ensure your ring fits perfectly.
