A semicircular structure made from alternating marbled materials, transitioning from darker to lighter shades, stands out against a beige background.
The image showcases a 3D object that appears to be a semi-circular structure with a series of concentric layers. The outer layer of the structure is a dark, marbled material with distinct veining patterns. As we move inward, the material transitions to a lighter, almost white hue with similar marbled patterns. The structure is set against a soft beige background, and there's a gentle gradient of light that casts a warm glow on the object, emphasizing its curves and contours.
