Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 18K yellow gold offers a secure, low-profile setting designed to cradle a 12 x 6 mm marquise stone, balancing bold presence with everyday comfort.

Crafted with precision in Williamsburg, the band’s smooth finish and subtle taper ensure it sits close to the hand without catching, ideal for those seeking a solitaire that wears effortlessly. The mounting’s streamlined prongs provide technical assurance, holding your chosen diamond firmly while maintaining a refined silhouette.

Each piece reflects a commitment to ethical jewelry: the lab-grown diamond option delivers clarity and brilliance with a smaller environmental footprint. The warm glow of 18K yellow gold complements the marquise’s fiery facets, creating a harmonious contrast that feels both modern and enduring.

Designed for daily life, this ring suits someone who values a confident yet understated statement—its shape elongates the finger, while the comfort fit invites continuous wear. Whether paired with a wedding band or worn solo, its low profile makes it glove-friendly and stackable.
