This professional jewellery CAD model features an elegant infinity twist engagement ring design with a pavé-set band and classic solitaire head. The flowing crossover structure adds a distinctive identity to the ring while maintaining strong commercial appeal and practical production feasibility.

The band is designed with intertwined curves that symbolize continuity and balance. Pavé stones are placed along the twist with consistent spacing and realistic proportions, creating continuous sparkle while preserving clean geometry for stone setting. The visual movement of the shank naturally leads the eye toward the center stone, enhancing the overall presence of the solitaire without appearing bulky.

The solitaire head is engineered with precise prong proportions to ensure secure stone holding and efficient bench setting. The head integrates smoothly with the twisted shoulders, maintaining both structural strength and visual harmony.

Wall thickness is controlled throughout the model to support reliable casting, durability, and long-term wear. The inner band remains smooth and comfortable, while the outer surfaces maintain clean transitions suitable for high-quality polishing and finishing.

The file structure is organized for easy resizing, customization, and adaptation across multiple size ranges, making this model highly suitable for professional CAD libraries and commercial resale.
