Thunder Egg Geode

Often mistaken for a simple rock from the outside, this genuine thunder egg holds a striking surprise inside. Once cracked open, it reveals swirling agate patterns in layered shades of white, gray, and brown with a soft, satiny center and occasional quartz sparkle. The internal design is formed naturally by volcanic activity—no two thunder eggs look alike, making each one a geological wonder.
