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 foundation in platinum offers a refined stage for a 7 x 3.5 mm marquise center, framed by smaller accents that promise subtle sparkle without overwhelming.

Crafted in platinum, the band is polished to a soft sheen and designed with a low-profile setting that rests comfortably against the finger, ideal for daily wear. Each prong is meticulously shaped to secure the marquise stone while allowing maximum light to animate its facets, enhancing the diamond’s signature tapered drama.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, which deliver clarity and brilliance with a reduced environmental footprint.

The slender band suits those who appreciate a graceful silhouette and pairs effortlessly with stacking rings or a wedding band. Its comfort fit and modest height make it glove-friendly and practical for an active lifestyle.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
