This Round Diamond Prong Set Engagement Ring 3D Model is a refined and production-ready jewelry CAD design created for professional manufacturing and high-end rendering. The ring features a classic round brilliant center stone secured in a strong four-prong setting, elevated for enhanced light performance and maximum brilliance.

The band is accented with large round side diamonds in a shared prong layout, giving the ring a bold yet elegant appearance. The stones are evenly spaced and precisely aligned to maintain symmetry and balance throughout the design. The slightly thicker shank provides durability while maintaining a luxurious profile suitable for engagement and bridal collections.

The structure has been engineered with real manufacturing standards. Proper stone seats, accurate prong thickness, and smooth internal surfaces ensure comfort and secure stone setting. The geometry is clean, manifold, and optimized for casting, resin printing, and CNC production.

This model is ideal for jewelry brands, custom designers, retailers, and CAD professionals who require ready-to-manufacture files with professional detailing and structural accuracy.

Designed in real-world millimeter scale for seamless production workflow.
