Luxury Jewelry Ad Video Prompt

A cinematic 15-second luxury jewelry ad featuring a confident young woman in a sleek black silk off-shoulder dress standing in a softly lit, high-end marble and glass penthouse at golden hour. The camera starts with a close-up of her hands slowly adjusting a diamond tennis bracelet, light catching every facet. It then pans upward to reveal layered heavy diamond necklace, matching statement earrings, and multiple diamond rings sparkling subtly as she moves. Soft, elegant orchestral ambient music builds. The lighting is warm but controlled, with sharp reflections of city skyline bokeh in the background. She turns slightly toward the camera with a calm, powerful expression, not speaking. Slow-motion shot as she brushes her hair back, diamonds catching intense light flares. Final 3 seconds: extreme close-up of the jewelry set with brand space left clean for logo and tagline like "Timeless Brilliance. Infinite Glow." Fade out on sparkling diamonds.
