Spider to Luxury Necklace Transformation

Hyper-realistic cinematic video of a woman wearing a strapless royal blue dress. A large, ornate gold spider brooch - encrusted with emerald green and sapphire blue enamel and dazzling diamonds - begins crawling up her hand, wrist, and across her chest. As she watches it with an anxious, startled expression, the spider transforms dynamically: its legs spread out into an elaborate, multi-tiered bib necklace of vibrant blue, purple, and green gemstones with a giant central sapphire. Her expression shifts from fear to awe and delight as she smiles at the stunning luxury necklace. Soft studio lighting, high contrast, smooth motion, 8k resolution.
