Close up of model face with solitaire diamond nose pin sparkling under soft light against gray blue wall

Generate a close-up hyper-realistic portrait of a dusky-skinned model wearing a single solitaire diamond nose pin. Use a Fujifilm GFX100 II medium-format camera with an 80mm f/1.7 lens at a 15° tilt from eye level to highlight the cheekbone structure and reflect diamond clarity. Lighting should include a soft frontal fill with a cool-tone beauty dish and subtle backlight that adds a soft halo around the model’s face. Backdrop: minimalistic textured concrete wall with gradient lighting from slate gray to steel blue. The diamond should show internal refraction and realistic sparkle with ultra-sharp clarity. Model makeup should be nude-toned, and her hair swept back into a clean bun. Zoom in close enough that only her eyes, nose, and lips are in frame. Place brand name vertically on the right edge: “[Brand Name] – Defined by Details.” Bottom left corner includes tagline: “One Spark. One Soul. Code: DN-09.” Ideal for use in minimalist print campaigns or cinematic IG Reels cover photos. Mood: sharp, intimate, premium.
