Small jagged glowing rock shard with rough dark textures

Imagine a small, jagged shard of rock, about the size of a thumb, glowing faintly with energy. The rock's surface is rough, with sharp edges and dark, natural textures, possibly resembling granite or basalt. Cracks run along the shard, and within these cracks, veins of bright blue or white electricity flicker, almost as if the shard is alive with power. The electric energy arcs and pulses within, casting an ethereal glow around the rock. You might see faint sparks jumping from the edges, indicating the high voltage contained within. The background could be dark, highlighting the glowing shard and its electric aura See more
