Physical Information
A Thunder Egg (or Thunderegg) is a nodule-like rock formation that forms in volcanic ash layers, most famously in Oregon, USA.
On the outside, they appear as dull, rough, spherical stones — but when cut open, they reveal beautiful interiors filled with agate, chalcedony, jasper, or opal.
Thunder Eggs form when gas bubbles or cavities inside cooling volcanic ash become filled with silica-rich solutions over millions of years.
Each Thunder Egg is unique, showing colourful bands, crystal pockets, or intricate patterns depending on the minerals present.
They typically have a tough outer shell and a hard, polished interior once cut and shaped.
Main sources include the USA (Oregon being the most famous), Germany, Mexico, Ethiopia, and Australia.
Metaphysical Properties
Thunder Egg is associated with grounding, transformation, and hidden potential.
Because they appear plain on the surface but contain beautiful crystals inside, they symbolize inner growth, self-discovery, and awakening.
Many use Thunder Eggs for emotional healing, releasing old patterns, and finding clarity during transitions.
They are believed to stabilize energy, bring protection, and help reveal one’s true path.
A powerful stone for those undergoing personal transformation or seeking deeper understanding.
