Nano Banana Prompt: Luxury Jewelry Banana AI Prompt for Fashion Editorials

Create an ultra-premium high-fashion jewelry editorial portrait with a dramatic selective color effect, where the entire image appears in rich high-contrast black and white, while only the luxurious sculptural gold necklace remains vividly colored in polished metallic gold. Set the scene against elegant heavy velvet curtains to create a timeless luxury editorial atmosphere. Feature an elegant woman wearing a structured couture hat, posed gracefully with refined facial expression and sophisticated styling. Ensure the necklace remains the visual centerpiece, preserving the exact original product shape, reflective details, and polished mirror-like surface without alteration. Use powerful directional side-top lighting to sculpt dramatic shadows and emphasize texture, depth, and premium fashion contrast. Capture the image with a 50mm prime lens at f/2.8, creating a cinematic shallow depth of field and editorial softness around the subject. The overall aesthetic should feel like a luxury Harper’s Bazaar-inspired fashion campaign — refined, bold, timeless, and magazine-worthy. AR: 3:2
