This radiant cut diamond engagement ring is designed with a perfect balance of brilliance and structure, featuring a rectangular radiant-cut center stone. The center diamond is secured in a strong four-prong setting that protects the corners while allowing maximum light reflection for enhanced sparkle and fire.

The design includes tapered side stones that complement the elongated shape of the radiant cut, creating a refined three-stone composition with elegant symmetry. The shank is adorned with round brilliant diamonds in a precise pave setting, adding continuous brilliance along the band while maintaining a clean and sophisticated profile.

An elevated gallery structure allows light to enter beneath the center stone, enhancing overall brilliance and depth. Smooth transitions between the head and shank ensure structural durability and comfortable daily wear. The inner band features a comfort-fit design for long-term usability.

This CAD model is professionally constructed with accurate stone seats, clean prong geometry, optimized wall thickness, and casting-ready structure. The model is designed to minimize post-production adjustments and support efficient manufacturing.

Ideal for bridal collections, engagement jewellery lines, custom designers, and jewellery manufacturers seeking a high-quality radiant cut diamond ring ready for production.
