Wand on a Comet: a 3D Space Render

Photorealistic 3D render of a magical wand planted into the icy surface of a comet, drifting through space. The wand is about 40 cm long, made of dark wood with silver filigree and rune engravings, with a glowing sapphire tip emitting a cyan light. The comet glows blue-white with crystalline ice, jagged edges, and a luminous tail sweeping behind. Surrounding space shows distant stars and a faint nebula; warm light on the wand contrasts with the cool reflections on ice. Depth of field with the wand in sharp focus and the background softly blurred. Rendered with high-resolution, ray-traced shadows, volumetric glow, and rich textures on wood, metal, ice, and crystal; cinematic mood and magical fantasy in space.
