Create a minimalist 3D render of a ring in the shape of a half-sun, viewed directly from the front. The ring should have a clean, simple design with smooth, elegant lines forming the semi-circular sun shape, with subtle, raised rays that add depth without overwhelming the minimalistic aesthetic. Render the ring in a neutral gray tone, resembling a basic 3D model in Blender, with a matte finish. The lighting should be soft and even, emphasizing the contours and subtle details of the design without creating harsh shadows or reflections. The background should be plain and white, enhancing the minimalist feel and keeping the focus entirely on the ring. The overall style should be modern, clean, and understated, with an emphasis on simplicity and the raw, untextured look typical of 3D models in the early stages of design.
