Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the length of the finger with quiet drama. This semi-set halo engagement ring foundation in 10K yellow gold offers a low-profile design, crafted to sit comfortably beneath daily gloves and sleeves without catching.

Hand-finished in Williamsburg, the band’s smooth contour and secure prong setting prepare it for a 10 x 5 mm marquise center stone, surrounded by a delicate halo that amplifies brilliance while maintaining a sleek profile. The warm yellow gold complements the diamond’s fiery sparkle, polished to a soft sheen that resists everyday wear.

Each lab-grown diamond chosen for this setting reflects a commitment to ethical sourcing and environmental mindfulness, embodying sustainable luxury without compromise.

Designed for those who appreciate refined geometry and subtle statement, this ring suits slender to medium finger sizes, its shape elongating the hand with architectural grace. The halo setting adds dimension while keeping the overall silhouette streamlined and glove-friendly.

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 truly your own.
