Create an ultra-realistic 4K square image featuring the inserted necklace displayed exactly as it exists in real life, with perfectly accurate shape, size, proportions, colors, materials, and textures. Every visible detail, including gemstones, metal reflections, and engravings, must appear razor-sharp, correctly rendered, and naturally integrated. Recreate the same composition as in the reference image: the necklace elegantly draped on a smooth, matte black display bust placed at the center of the frame, surrounded by a rich, deep red satin fabric that folds and flows naturally around the base. Use soft, directional lighting from the upper left to create refined highlights across the necklace and subtle shadows that fall gently on the fabric and background. Maintain a dark, seamless black backdrop that enhances the contrast between the red satin and the metallic tones of the jewelry. Preserve a luxurious, cinematic atmosphere with balanced contrast, smooth gradients, and delicate light reflections that emphasize the product’s elegance and realism. The overall mood should feel premium, refined, and gallery-like, showcasing the necklace as the central focus within a dramatic and sophisticated visual environment.
