Did you ever hear about the rock superstition? Well, some believe that you should never take a rock home when you’re traveling. Why? It’s apparently bad luck.
There are some items people encourage tourists to not pick up and bring home as a souvenir. Rocks and sand are the most common, especially in Hawaii.
According to this superstition, Pele―the Hawaiian goddess of volcanoes―curses anyone who removes lava rocks from the islands with severe misfortune. I’m not sure if I believe in these superstitions, but I guess it’s better safe than sorry. There are other legends too related to rocks, but this one is the most popular with Islanders.
