This Radiant Cut Diamond Eternity Shank Engagement Ring 3D CAD model is professionally developed for luxury jewellery manufacturing and premium bridal collections. The ring features a bold radiant-cut center stone secured with precisely engineered prongs, combined with a full eternity-style shank set with round brilliant diamonds.

The radiant-cut center stone blends the elegance of a rectangular silhouette with the brilliance of a faceted cut, offering both sparkle and structure. The elevated basket setting is designed to maximize light performance while ensuring casting stability and long-term durability.

The eternity shank showcases a continuous row of round diamonds in a shared prong style, delivering uninterrupted brilliance around the band. The side gallery includes properly structured supports and open areas for cleaning access and secure stone setting. The interior features a smooth comfort-fit profile for enhanced wearability.

This model is created with accurate stone seats and proper metal thickness, making it suitable for gold, white gold, rose gold, platinum, and other precious metals. Clean and optimized geometry ensures reliable production and allows easy resizing or stone dimension adjustments in Rhino or compatible CAD software.
