polished stone surface dark granite smooth
Prompt
Photorealistic macro background texture of a smooth polished dark granite stone surface, filling the entire frame with subtle natural mineral speckles, charcoal gray, deep blue-black, muted tan, and faint silver flecks. The surface should feel cool, dense, and refined, with a low satin reflection rather than mirror gloss, showing gentle variations in grain and tiny inclusions across the slab. Compose as a clean, edge-to-edge abstract stone backdrop with no objects, no labels, and no visible seams, suitable for commercial design use. Soft diffused daylight from the upper left creates delicate highlights and shallow tonal gradients, calm and minimal mood, shot straight-on with a 50mm macro lens, f/5.6, crisp detail across the texture.
