Lab-Grown Diamond Engagement Ring

Sunlight 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 in 10K yellow gold frames a 9 x 4.5 mm marquise center, designed to balance presence with everyday ease.

Crafted with a low-profile setting, the halo gently cradles the center stone, enhancing its glassy, tapered elegance without adding bulk. The band’s smooth finish and modest width ensure a comfortable fit beneath gloves or alongside stackable bands, making it a practical choice for daily wear. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of polish and symmetry.

Our commitment to ethical jewelry is reflected in the use of a lab-grown diamond, offering clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate architectural refinement paired with understated comfort—ideal for hands that favor elongated shapes and a secure, low-profile mount. The semi-set design invites you to select a center stone that resonates personally, allowing for a truly custom expression.

Resizing is straightforward, handled carefully in-studio to maintain the integrity of the halo and band proportions.
