Albanians believed the supreme powers of thunderstones were formed during lightning strikes

Albanians believed in the supreme powers of thunderstones (kokrra e rrufesë or guri i rejës), which were believed to be formed during lightning strikes and to fall from the sky. Thunderstones were preserved in family life as important cult objects. It was believed that bringing them inside the house would bring good fortune, prosperity, and progress to people, especially in livestock and agriculture, or that rifle bullets would not hit the owners of thunderstones. Thunderstone pendants were believed to have protective powers against the negative effects of the evil eye and were used as talismans for both cattle and pregnant women.
