golden geometric frame 3d model

Create a high-quality 3D model of a gold-colored geometric sculpture with an abstract and modern design. The object should feature interlocking triangular and rectangular shapes, forming optical illusions like the Penrose triangle. Include smooth and slightly textured metallic surfaces with polished gold reflections. The structure should appear symmetrical and visually complex, suitable for use as a decorative item or jewelry piece. Ensure realistic lighting and shadows to emphasize depth and perspective.
