Marquise Cut Lab Grown Diamond Engagement Ring | Maria Grandeur

Discover an magnificent blend of structural majesty, modern art deco geometric lines, and timeless brilliance with the Maria Grandeur Lab Grown Diamond Engagement Ring by Jewel Nests. Expertly engineered for the discerning individual who seeks an extraordinary statement piece, this ring pairs architectural metalwork with a distinctive multi-stone silhouette.

The defining characteristic of this engagement ring is its hybrid half-bezel setting paired with four delicate claw prongs. A grand marquise-cut center diamond is cradled securely at its North and South points by protective golden bezel caps, while four subtle prongs secure the curved sides. Flanking this centerpiece on each shoulder is a stepped side-stone arrangement, featuring a horizontally bezel-set baguette diamond leading down to a sharp, brilliant trillion-cut stone.

Product Highlights
Hybrid Half-Bezel & Prong Architecture: The Maria Grandeur offers maximum protection for delicate marquise tips by encasing both ends in solid precious metal bezel caps. The open sides are held by four sleek prongs, ensuring exceptional light entrance and complete security.

Stepped Baguette & Trillion Accents: Giving a modern geometric twist to traditional side-stone rings, the shoulders feature a tiered layout. The step-cut baguette diamonds offer clean, mirror-like reflections that transition seamlessly into the multi-faceted fire of the trillion-cut diamonds.

Artisanal Tapered Band: Engineered with a dramatic, comfortable taper, the shank measures a delicate 1.60 mm at the top shoulders to emphasize the central stone cluster before widening smoothly to a substantial 3.0 mm at the base for structural balance.

Signature Inside Base Diamond: In alignment with Jewel Nests' signature design hallmarks, a secret princess-cut diamond is embedded flush into the bottom base of the band, serving as an intimate, hidden token of your romance.

Lower-Profile Daily Wear Comfort: The setting is built close to the finger, reducing daily catching while maintaining a grand top-view presence.
