This Marquise Diamond Engagement Ring 3D model is crafted with elegant proportions and refined detailing, suitable for professional jewellery manufacturing. The centerpiece features a precisely shaped marquise-cut diamond secured with protective prongs at the tips and sides, ensuring both brilliance and structural stability.

The elongated silhouette of the marquise cut creates a graceful and sophisticated appearance, enhanced by a delicate micro pavé band that adds continuous sparkle along the shank. The gallery structure is carefully engineered to provide strong stone support while allowing optimal light reflection for enhanced brilliance.
