Good morning! For today’s Crystal Thursday, we’re diving into something similar to, but different from, last week’s Omarlluk post: the Hag Stone. Also called witch stones, holey stones, or adder stones, a hag stone is any stone with a naturally formed hole running through it.
When people think of hag stones, they often picture ocean-worn stones from the coasts of Ireland, England, and other parts of Europe. However, freshwater Hag Stones can also be found along rivers, lakes, and even the Great Lakes.
A stone begins its transformation with a weak spot. Over years or centuries, water erodes that area until a smooth opening forms. Limestone is the most common material, but sandstone, basalt, chert, and even coral can become a Hag Stone given enough time. In saltwater environments, pholad clams assist the process by burrowing into softer stone.
While researching, I wondered whether a stone could be both a Hag Stone and an Omarlluk. Many people think they’re interchangeable, but they aren’t. Omarlluks are glacial erratics, made of greywacke, while Hag Stones can form from almost any material. Some have Omar-like pits, but these are simply areas that haven’t fully eroded. One stone can be both, but it would have to begin as an Omar.
Hag stones appear in Celtic, English, and Norse folklore, going back centuries. They were used for protection, hung over doors to ward off negative energy, worn as amulets to prevent nightmares, and carried by sailors for safety at sea. It was said that looking through the hole allowed one to see spirits or faeries hidden from ordinary sight.
Hag Stones represent passage and perception. The hole forms a doorway, making it powerful for protection, transformation, and clarity. Because they form through erosion, they’re also used to release old emotions and embrace new energy.
I hope you’ve enjoyed this look at Hag Stones. If one calls to you, hold it during meditation or hang it where energy enters your home. And if you ever find one, whether on an ocean beach or along the Great Lakes, know you’ve discovered something ancient and special.
