Bradhamel art style. A close-up macro shot of a single, irregularly shaped translucent crystal gemstone with deep purple and electric blue internal luminescence, glowing with golden-yellow vein-like patterns resembling cosmic filaments, resting on dark, rough volcanic rock; the crystal is partially encased in a jagged black mineral crust at its top edge, catching soft directional light that highlights its facets and inner glow against a blurred, dimly lit background of earthy tones, emphasizing the contrast between the vibrant, mystical interior and the rugged, grounded exterior, rendered with hyperrealistic texture and depth-of-field focus.
