[Photo] Macro photography of a seamless surface of deep, polished obsidian-black marble, prominently featuring intricate, organic gold veins that elegantly meander throughout. Dramatic side lighting rakes across the texture, casting long, sharp shadows that profoundly emphasize the three-dimensional depth, microscopic imperfections, and natural undulations of the highly reflective stone. The intense light brilliantly catches and reflects off the shimmering gold veins, revealing their true metallic luster and warmth as they interact with the cool, dark marble, highlighting their subtle relief and irregular, luxurious placement. Hyper-realistic, sharp focus, intricate details, 8k, ultra-high resolution, 4k texture, clean composition, no distortion.
