This contemporary statement ring 3D model features a bold wide-band silhouette with a central split-top design, highlighted by a horizontally set marquise-cut gemstone held in a refined prong setting. The smooth polished exterior creates a clean, architectural appearance, while the geometric openwork pattern inside the band adds intricate detail and helps reduce unnecessary material volume. Presented in a yellow-gold finish with a red gemstone for visualization, the design can be adapted to other metals and stones. The model is specified in EU ring size 57 with a stated 0.5 mm thickness and is suitable for jewelry visualization, customization, prototyping, casting, and production preparation. Dimensions, stone tolerances, prong strength, and wall thickness should be verified for the intended manufacturing process.
