This contemporary jewelry 3D model features a bold sculptural ring with a wide tapered band, a distinctive open U-shaped upper profile, and a round blue cabochon stone secured in a clean bezel setting. The polished exterior creates a refined luxury appearance, while the intricate geometric lattice inside the band adds decorative detail and reduces unnecessary material volume. Designed in EU ring size 57 with a specified thickness of 0.6 mm, this model is suitable for jewelry visualization, CAD presentation, prototyping, casting preparation, and 3D-printing workflows. The design can also be adapted to different ring sizes and thickness specifications.
