Create a hyper-realistic macro photograph depicting a miniature galaxy swirling within a single, perfectly cut amethyst drop earring for the Accessories shots. The image features overlay text 'Check Comment for Prompt' at the top and 'aisuperhub.io' at the bottom. The earring hangs suspended, its faceted surface reflecting soft light. Inside the amethyst, a vibrant, cosmic nebula is visible, with tiny stars, gas clouds, and swirling galaxies, appearing impossibly vast and real, a universe contained, shimmering with ethereal light. Details to include: Intricate cosmic dust lanes and glowing stellar nurseries; Subtle gravitational lensing effects within the 'gemstone cosmos'; A tiny, distant spiral galaxy visible deep within the gem's core; The earring's polished silver setting with minute engravings; Micro-reflections of the surrounding studio light on the earring's outer facets. The background is a velvety dark void, subtly textured to imply infinite depth, enhancing the contrast with the glowing interior of the gem. Minimal, elegant, and clean, it ensures the focus remains entirely on the earring and its impossible contents, suggesting a high-end studio product shoot. Dramatic, ethereal backlighting emanates from within the amethyst itself, casting soft, colorful glows onto the surrounding silver. A single, focused, soft-box light from the front highlights the external facets of the earring, creating sharp, yet delicate, reflections. The overall intent is mystical and luxurious. The color palette features deep purples, cosmic blues, fiery oranges, and shimmering golds for the nebula, contrasted with the cool silver of the setting and the dark, infinite black of the background. The mood is mystical, awe-inspiring, and luxuriously surreal. This is a hyper-realistic, studio product photography, cosmic fantasy, macro-photorealistic, high-detail, ethereal, luxury advertising masterpiece.
