Lab-Grown Diamond Engagement Ring

The elongated silhouette of a 10 x 5 mm marquise diamond catches the eye with its tapered points, lending a subtle drama that elongates the finger gracefully. This semi-set solitaire ring foundation in 10K yellow gold offers a streamlined, low-profile setting designed for everyday wear, balancing presence with comfort.

Crafted in Williamsburg, Brooklyn, the band’s gentle curve and secure prong arrangement ensure the stone sits close to the hand, minimizing snagging while maintaining brilliance. The warm hue of the yellow gold complements the marquise’s fiery facets, finished with a smooth comfort fit that feels natural from morning coffee to evening strolls.

Each ring foundation is made with lab-grown diamond clarity standards, reflecting a commitment to sustainable, ethical jewelry without compromise on sparkle or structure.

Ideal for those seeking a distinctive yet practical engagement ring, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its low profile makes it glove-friendly and unobtrusive for daily life.

Resizing is available to ensure a precise fit, and the semi-set design invites you to select a center stone that resonates personally, with expert guidance from our Brooklyn studio.
