Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring foundation in warm 14K rose gold offers a delicate frame for a 5 x 3 mm marquise center, designed to sit low and close to the hand for everyday grace.

Crafted with precision, the band’s slender profile and secure prong setting ensure comfort and durability without excess height. The rose gold’s gentle blush complements the diamond’s fiery facets, while the mounting’s refined finish reflects careful inspection and expert handwork in our Williamsburg studio.

Each piece embraces the clarity and sustainability of lab-grown diamonds, aligning with a mindful approach to fine jewelry. The low-profile design suits those who prefer a ring that layers easily with wedding bands or stackable accents, and its balanced shape flatters slender to medium finger sizes.

Should you wish to adjust the fit, resizing is available to maintain comfort and wearability. This semi-set invites you to select a marquise stone that resonates personally, making the ring uniquely yours.
