Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc that seems to stretch the hand with quiet elegance. This semi-set three-stone engagement ring in platinum offers a refined frame for an 8 x 4 mm marquise center, its pointed ends balanced by two smaller side stones that echo its graceful shape.

Crafted in cool, polished platinum, the mounting features a low-profile setting that nestles close to the finger, designed for everyday wear without catching or discomfort. Each prong is meticulously finished to secure the stones while allowing maximum light to pass through, enhancing the marquise’s signature brilliance and subtle fire.

Our commitment to ethical jewelry is reflected in the choice of a lab-grown diamond, offering clarity and sparkle with a reduced environmental footprint.

The slender band and low profile make this ring ideal for those who appreciate a balance of statement and subtlety, fitting comfortably beneath gloves or alongside stackable bands. The marquise shape’s elongating effect flatters a variety of hand sizes, lending an architectural yet romantic presence.

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