This Marquise Cut Twist Shank Halo Ring CAD model is designed to highlight the elongated elegance of a marquise center stone, enhanced by a refined halo and a flowing crossover shank.

The marquise-cut center stone is secured with protective prongs positioned to safeguard the pointed tips while maximizing light exposure. A precisely contoured halo surrounds the center stone, following its elongated silhouette and enhancing overall brilliance without overpowering the design.

The defining feature of this ring is its twisted crossover shank. One arm of the twist is adorned with pavé-set diamonds that extend along the upper band, creating continuous sparkle from multiple viewing angles. The second arm features a smooth, polished surface that provides contrast, structural balance, and comfortable wear. The intertwining design adds movement and dimension while maintaining a clean, luxury aesthetic.

The under-gallery is carefully engineered to support the halo and center setting securely. Stone seats, prong thickness, and wall tolerances are optimized for casting, stone setting, and finishing. Surfaces are clean and production-ready, making the model suitable for resin printing and precious metal casting.

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 ideal for bridal collections, custom engagement rings, and premium jewellery manufacturing.
