Infinity Stone Aglow in a Volcanic Crater

Hyper-detailed digital painting of a single Infinity Stone resting at the bottom of a volcanic crater. The gemstone is a perfect sphere with iridescent facets that refract molten lava light. Colors shift through crimson, sapphire, emerald, violet, and gold, while fractal energy threads halo the stone. Surrounding crater walls are jagged basalt and glowing lava rivers; steam plumes and ash clouds fill the air. Floating embers and fine particle effects drift as the stone's glow reflects on wet rock and magma pools, casting dramatic neon highlights. The style blends painterly digital art with cinematic, high-dynamic-range lighting, volumetric fog, and razor-sharp textures. 4k resolution, concept art quality.
