This round three-stone engagement ring 3D CAD model showcases a timeless and balanced design crafted for fine jewellery production. The centerpiece features a brilliant round diamond secured in a refined four-prong setting, allowing optimal light performance and maximum brilliance. The prongs are carefully proportioned to protect the stone while maintaining an elegant and minimal appearance.

On each side of the center stone, two round brilliant diamonds are positioned symmetrically to enhance overall sparkle and create a harmonious three-stone composition. The side stones are designed to complement the center without overpowering it, offering a classic engagement ring aesthetic suitable for modern and traditional bridal collections.

The gallery structure is engineered with reinforced supports to ensure durability during casting and long-term wear. The under-gallery is clean and open, allowing light flow beneath the stones while maintaining structural integrity.

The shank features a smooth, comfort-fit interior and balanced thickness for reliable casting in gold, platinum, or silver. The proportions are optimized for production efficiency, secure stone setting, and high-quality finishing.

This model is fully production-ready with clean, watertight geometry suitable for high-resolution 3D printing, CAM workflows, and professional rendering. Ideal for jewellery manufacturers, custom designers, and bridal collections seeking a dependable and elegant three-stone ring base model.
