About Stones: Thunder Egg

thunderegg2

Astrological Sign: Gemini
Chakra: Heart
Lore: Thunder eggs are named after a myth which tells that they were thrown upon the earth by angry gods. They are used to attract like-minded people, instill a sense of community, and to decrease anger and hostility.
Geology: Thunder eggs are spherical agate-filled nodules. All of them have a characteristic star frame, but no two are ever alike. Agate, a form of chalcedony, belongs to the quartz family of minerals. Volcanic action created cavities and gas pockets that were later filled by silica. The cavities then became solidified, producing the agates dug today.
