Create an ultra-realistic 4K close-up image of a woman’s lower face, neck, and collarbones wearing uploaded photo. The product must appear exactly as it is in shape, size, proportions, material, surface texture, engravings, logos, text, and colors, with no alteration or stylization. Place the product naturally around the neck in a realistic, elegant fit, resting against smooth skin with warm undertones. Lighting should be soft and frontal, slightly angled from above, creating gentle, even highlights across the skin and the product while maintaining subtle shadows in the collarbone hollows and beneath the product links or curves. The product’s reflective surfaces should display crisp but diffused highlights, preserving accurate brilliance without overexposure. The background should be a deep, soft black or charcoal gradient with no texture or distractions, fading subtly to enhance a sense of minimalism and luxury. The model’s skin should appear flawless, smooth, and natural, with warm golden undertones and soft gradients of light and shadow. Composition must be tightly cropped: the upper frame cuts just below the nose, and the lower frame includes the upper chest and collarbones, ensuring the focus remains on the product. No additional elements, props, or distractions. Final image must be in 1:1 square format, ultra-detailed, premium, and photorealistic.
