This premium round-cut diamond engagement ring 3D model features a bold triple band structure combined with refined pavé detailing. The centerpiece is a brilliant round-cut stone secured with four strong prongs, designed to maximize light performance and maintain structural integrity for manufacturing.

The triple shank design creates a layered, luxurious appearance while providing enhanced strength and balance. Two outer bands are adorned with precisely aligned round pavé diamonds, delivering continuous sparkle and a high-end bridal aesthetic. The clean symmetry and smooth surfaces make this model suitable for both classic and contemporary jewellery collections.

The model is built with accurate stone seats, proper prong thickness, and clean geometry to ensure smooth casting and reliable production. It is optimized for CAM processes and high-quality rendering, making it ideal for professional jewellery designers and manufacturers.
