Lab-Grown Diamond Engagement Ring

The elongated silhouette of the 10 x 5 mm marquise diamond hints at quiet drama, its tapered points drawing the eye along the finger with subtle elegance. This semi-set halo ring foundation in 18K white gold offers a low-profile setting designed to cradle your chosen center stone securely while maintaining everyday comfort.

Crafted with precision in Williamsburg, Brooklyn, the band’s smooth finish and balanced weight ensure it sits naturally, whether worn solo or stacked. The halo setting frames the marquise shape with delicate pavé accents, enhancing brilliance without adding bulk—ideal for glove-friendly wear and daily life.

Each piece reflects a commitment to sustainability, featuring a lab-grown diamond center that combines clarity and ethical sourcing without compromise. The 18K white gold band is polished to a refined sheen, inspected meticulously to meet exacting standards of fit and finish.

Designed for those who appreciate architectural grace paired with practical wearability, this ring suits slender to medium finger profiles and adapts well to resizing if needed. Its semi-set nature invites you to select a marquise diamond that resonates personally, making the design uniquely yours.
