Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to cradle the hand. This semi-set halo engagement ring foundation in cool platinum invites your choice of a 6 x 3 mm lab-grown marquise center, designed to amplify the stone’s graceful drama with a surrounding halo that scatters light like morning dew.

Crafted with meticulous attention, the platinum band offers a low-profile setting that rests close to the finger, balancing presence with everyday ease. Each prong is hand-finished to secure the stone while maintaining a refined silhouette, and the halo’s pavé diamonds are precisely set to enhance brilliance without bulk.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and origin—ethical jewelry made with care for both people and planet.

The slender band suits a variety of hand shapes, its comfort fit allowing for effortless wear and compatibility with stacking rings or a wedding band. The marquise shape’s elongating effect complements slender fingers, while the halo adds a subtle vintage whisper to a modern design.

Should you wish to adjust the band size, resizing is available with expert craftsmanship to preserve the ring’s integrity and finish.
