Presenting a refined Princess Cut Hidden Halo Engagement Ring CAD model developed for precision jewellery manufacturing and premium bridal collections.

This design features a striking princess-cut center stone secured with four strong yet elegant claw prongs positioned precisely on the corners. The prong placement is engineered to protect the delicate corners of the square stone while maintaining a clean and balanced appearance from the top view.

A hidden halo of round accent diamonds is positioned beneath the center stone, adding brilliance from the side profile without interrupting the sharp geometric look of the princess cut. This concealed halo enhances sparkle while preserving a minimal and modern top aesthetic.

The elevated gallery structure allows optimal light penetration into the center stone, enhancing its brilliance and fire. Structural cross bars and internal supports are carefully modeled to provide strength during casting and long-term durability during wear.

The shank is adorned with a single row of pave-set round diamonds, evenly distributed for balanced brilliance and smooth finishing. Each stone seat is precisely modeled to ensure efficient setting and accurate production results.

The under-gallery design ensures structural integrity while maintaining comfort for everyday wear. The overall geometry is clean, manifold, and optimized for casting and high-resolution 3D printing.

This model is suitable for luxury engagement ring collections, custom jewellery projects, and commercial production.

Compatible with yellow gold, white gold, rose gold, and platinum manufacturing.
