Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that draws the eye along the finger. This three-stone semi-set engagement ring in 10K yellow gold offers a refined foundation for a 12 x 6 mm marquise center stone, designed to sit low and close to the hand for everyday grace.

Crafted with precision, the band’s gentle curve and secure prong setting ensure comfort and durability without excess height. The warm glow of 10K yellow gold complements the marquise’s fiery facets, while the semi-set design invites your choice of center diamond, allowing for a personalized expression of brilliance. Each piece is hand-finished in our Williamsburg studio, inspected for flawless fit and finish.

Our commitment to lab-grown diamonds means this ring carries a clear ethical edge—sustainably created with the same optical properties as mined stones, but with a smaller environmental footprint.

Ideal for those who appreciate a sleek profile and a ring that layers effortlessly with wedding bands or stackable styles. Its low profile and secure setting make it glove-friendly and suited to an active lifestyle.
