Luxury Red Gemstone Ring

Generate a hyper-realistic image of a colossal silver ring with a large, oval-cut red gemstone, surrounded by smaller white gemstones on the band, standing upright on a wet, dark grey tiled rooftop, with a woman in a flowing black evening gown standing beside it, gazing upwards, set against a dramatic, cloudy grey sky with a cityscape in the background, featuring sleek, modern architecture and a moody, overcast atmosphere, with the ring and the woman reflected in the wet tiles, and subtle lighting that accentuates the textures and details of the jewelry and the surroundings, and with a sense of luxury, sophistication, and drama, and with the image being a high-end design editorial or campaign photograph, with realistic lighting, natural shadows, detailed textures, accurate mockup construction, and refined styling.
