Generate an ultra-high-resolution, visually stunning macro photograph of a [PRODUCT_TYPE_e.g., diamond engagement ring] featuring a [METAL_TYPE_e.g., platinum] band with a [STONE_CUT_e.g., brilliant round] cut [GEMSTONE_e.g., diamond]. The shot should be taken at an extreme macro angle (100mm macro lens equivalent, f/2.8 aperture) with a shallow depth of field, focusing sharply on the facets of the main gemstone and the intricate details of the setting. Utilize a three-point studio lighting setup: a softbox key light positioned at 45 degrees, a fill light at 90 degrees with a reflector, and a strong rim light from behind to create dramatic sparkle and highlight the contours. The background should be a subtly blurred, luxurious [BACKGROUND_MATERIAL_e.g., black velvet or polished marble] to provide contrast. Emphasize light refraction, intricate reflections, and the brilliant sparkle, reminiscent of high-end advertising photography seen in Tiffany & Co. or Cartier campaigns. The atmosphere should be elegant, sophisticated, and aspirational. Output in 4K resolution, capturing every micro-detail and shimmering highlight.
