Design a detailed 3D model of a weathered stone wall plaque with an arched structure and intricate carvings. Flank it with ornamental columns featuring textured bases and caps. Frame the central panel with a patterned metal border with subtle engravings. The stone should show cracks and erosion, while the metal has a worn patina. Focus on realism with material imperfections and natural lighting for an authentic look.
