3D CAD Model of a Contemporary Multi-Band Ruby and Gold Ring

This is a digital three-dimensional Computer-Aided Design (CAD) model of a complex, contemporary piece of fine jewelry. The design features a multi-band architectural structure, likely intended to be rendered in 18k or 24k yellow gold based on the vibrant yellow digital sheen. The ring consists of four distinct, parallel bands joined by a vertical spanning element. Specifically, it features a central large oval-shaped red gemstone, likely representing a ruby, set in a bezel or pressure setting. Flanking this central stone are numerous small, square-cut red stones, possibly rubies or garnets, meticulously arranged in channel settings along the top ridges of the outer bands. The construction is highly geometric with sharp, angular peaks on the bands, reflecting a modern or avant-garde style. As this is a digital asset within a software interface (likely Blender with the JewelCraft add-on), it represents the 'perfect' theoretical form without any wear, patina, or physical damage. The interface shows detailed parameters for material properties like 'Metallique', 'Rugosité' (Roughness), and 'IOR' (Index of Refraction), indicating a high-quality professional rendering process meant to simulate realistic light interaction and craftsmanship of precious metals and gemstones.
