Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set five-stone engagement ring in 10K white gold offers a refined stage for a 9 x 4.5 mm marquise center, inviting your choice of a lab-grown diamond to complete its poetic line.

Crafted with a low-profile setting, the band’s gentle curve and secure prongs ensure daily wearability without catching or discomfort. Each detail is hand-finished in our Williamsburg studio, where precision meets subtle artistry, and every piece undergoes rigorous inspection to meet exacting standards.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry, reducing environmental impact while embracing clarity and brilliance that rivals mined stones.

The slender band complements slender to medium finger sizes, its five-stone arrangement adding a soft shimmer that pairs beautifully with stacking rings or worn solo. Its comfort fit and modest height make it glove-friendly and suited for everyday life.

Should you wish to adjust the band size, resizing is available with care to preserve the ring’s delicate balance and finish.
