Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set three-stone ring invites your choice of a 6 x 3.5 mm marquise center, its distinctive shape lending a graceful taper that visually lengthens the finger.

Crafted in cool, enduring platinum, the mounting features a delicate balance of strength and refinement. Each prong is meticulously hand-finished to cradle the stone securely while maintaining a low-profile setting that slips comfortably beneath gloves or sleeves. The side stones frame the center with subtle brilliance, enhancing the ring’s architectural elegance without overwhelming daily wear.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and sparkle with a lighter environmental footprint.

Designed for those who appreciate artisanal detail and a refined silhouette, this ring suits slender to medium finger shapes and layers effortlessly with stackable bands. Its comfort fit and modest height ensure it remains an enduring companion through everyday moments.

Should you need adjustments, resizing is handled in-house with care to preserve the ring’s structural integrity and finish.
