Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident, architectural edge. This semi-set engagement ring frame in 18K white gold offers a sleek, modern-minimal foundation designed to highlight a 9 x 4.5 mm marquise center stone of your choosing.

Crafted in Williamsburg, Brooklyn, the band’s clean lines and low-profile setting ensure comfortable daily wear while the precise accents add refined structure without distraction. The 18K white gold is hand-finished for a smooth, cool touch that complements the stone’s sharp geometry.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, offering clarity and brilliance without compromise. This mounting’s streamlined silhouette suits slender fingers and pairs effortlessly with stacking bands or a wedding band.

Resizing is available to ensure a perfect fit, and the semi-set design allows you to select a marquise diamond that matches your vision and budget. Lead times vary slightly depending on stone selection but are communicated clearly during consultation.
