A purple, amethyst-like crystal, shaped like a hexagonal prism, glows from within with an intense light that seems to pulse with ancient energy. The crystal possesses translucent facets that refract light in multiple directions, creating sparkles and bright points on its polished surface. The crystal is partially embedded in a dark gray rock formation, with mineral veins snaking around its base, encircling it as if the stone had naturally formed around it over millennia. Small, spiky black crystals emerge from the surrounding rock, forming a natural frame that enhances the purple glow of the main crystal. The setting is a completely black, hazy cavern, where distant rock formations and tiny glimmers of other luminescent minerals are glimpsed, creating an eerie space that makes the crystal the focal point of the image. The lighting is dramatic, with the crystal as the primary light source, projecting a diffuse fluorescent purple halo that gradually fades into the surrounding darkness, subtly revealing the textures of the wet stone. The atmosphere evokes a mystical and powerful feeling, as if the crystal contained ancient energy trapped in the earth for eons. Technically, the image possesses a photorealistic quality with high contrast, shallow depth of field, and perfect definition of the textures of the transparent crystal and rough stone.
