Luxury model in satin gown wearing bold emerald necklace against dark smoky backdrop with gemstone sparkle

Create a hyper-realistic image of a luxury fashion model in a black satin gown wearing a large emerald-encrusted statement necklace. Background is a textured charcoal-black with smoky gradient. Lighting setup includes Rembrandt lighting with a single top-down softbox, and two kicker lights aimed at the necklace to catch emerald facets. Camera: Phase One IQ4 150MP with 100mm f/2.8 macro lens at 45° angle. Focus on sharp gemstone details — visible facets, color depth, and inner reflections. Add ambient smoke for texture with cold blue-green tones in the mid-background. Place brand name bottom right: “[Brand Name] – Eternal Emeralds.” Include bold tag at top left: “Signature Statement | #EMR-LUXE.” Mood: fierce, dramatic, bold. Ideal for magazine centerfold and high-end billboard use.
