TASK: Using the uploaded jewelry reference, seamlessly place the {necklace} onto {neck} with perfect anatomical alignment and correct real-world scale.
PRESERVE: Keep the original craftsmanship exactly — the stone setting, gem cut, facets and metal structure identical to the reference. Same shape, same proportions, same details. Do not redesign, do not add or remove elements.
PHYSICS: Realistic weight interaction with the skin and a subtle, soft contact shadow where the piece touches the body. The piece hangs and rests naturally with gravity.
SURFACE: Physically accurate reflections on the metal, fine microtexture detail, high-polished finish, true-to-life gemstone refraction and sparkle, accurate metal color and warmth.
LIGHT: Soft diffuse studio lighting with controlled highlights and a natural shadow gradient. Flawless neutral background, soft cinematic light.
STYLE: Luxury high-jewelry campaign photography, photorealistic integration, ultra-high detail, 4K. Fashion editorial, surreal-elegant, striking contrast of raw beauty and luxury.
IDENTITY: Preserve the model's identity, facial features, skin texture and freckles exactly as in the avatar. No face morphing, no identity drift.
