Create an ultra-realistic 4K square image featuring the inserted necklace displayed exactly as it is in real life, with 100% accurate shape, size, proportions, color, material, and every visible detail rendered perfectly sharp and naturally integrated. Present the necklace draped naturally around an elegant sculptural mannequin bust with an elongated neck and stylized facial features, positioned in a graceful side profile. The necklace must rest precisely around the neck, without extending toward the ears or any other part of the head. There must be no additional jewelry, chains, or accessories on the mannequin. The mannequin should have a smooth matte surface in deep greenish-gray tones with a subtle satin sheen that softly reflects light without glare. It should stand on a circular pedestal of the same tone and texture, forming a cohesive and minimalist stage for the jewelry. Illuminate the scene with soft, directional lighting from the upper left, producing gentle highlights along the mannequin’s contours and the jewelry’s metallic and gemstone surfaces, while casting long natural shadows toward the lower right. Maintain cinematic depth and contrast with smooth tonal transitions that emphasize the neck and face silhouette. The background should be a seamless continuation of the same muted green tone, softly blending with the subject to create a tranquil and luxurious atmosphere. The overall color palette must remain harmonious, dominated by deep greens, warm gold accents, and subtle reflections that highlight the craftsmanship and realism of the necklace. The final image must feel premium, artistic, and gallery-like, preserving full photorealism, accurate proportions, and a serene, sculptural mood.
