Restage my jewellery photo as a luxury product shot. Place the piece on a deep matte background — near-black or a dark stone — with a soft pool of light isolating it. Lighting: a large soft source giving long clean gradients across the metal, plus one small hard source making a sharp sparkle in the stones. Real reflections and refraction in the gems. Macro sharpness on the setting and the stone, the background falling fully out of focus. Keep the metal colour, stone colour and setting exactly as they are.
“Use it” opens the editor with this prompt already loaded — add your photo and generate. Copy works anywhere else: ChatGPT, Gemini, Midjourney.
Metal needs gradients, stones need a hard light. That's why this asks for two sources.
