This Radiant Cut Twist Shank Halo Ring CAD model is designed to combine the sharp brilliance of a radiant-cut center stone with the fluid elegance of a crossover pavé band. The result is a modern engagement ring that balances structure, sparkle, and movement.

The radiant-cut center stone is secured with four strong prongs positioned to protect the trimmed corners while maximizing light entry. A finely contoured halo surrounds the center stone, following its rectangular geometry and enhancing overall brilliance. The halo adds depth and dimension without overpowering the clean lines of the radiant cut.

The twisted crossover shank is the signature design feature. One arm of the band is set with pavé diamonds that extend along the upper shank, creating continuous sparkle from multiple angles. The opposing arm remains smooth and polished, offering visual contrast and reinforcing structural strength. The intertwining design provides a dynamic appearance while maintaining comfortable wear and balanced proportions.

The under-gallery and setting structure are engineered for durability and secure stone placement. Accurate stone seats, clean surfaces, and optimized wall thickness make this model suitable for resin printing, casting, stone setting, and final finishing.

This CAD model is compatible with gold, platinum, silver, and other precious metals. It supports natural diamonds, lab-grown diamonds, and alternative gemstones, making it suitable for bridal collections, custom engagement designs, and premium jewellery manufacturing.
