Hag stones or holey stones (sometimes also called witch stones, adder stones, fairy stones, or serpent eggs) are stones with a naturally occurring hole that goes all the way through. They are often created by burrowing creatures and worn straight through by water over time. A string or chain might be threaded through the hole to create a necklace or talisman.
On the hunt
I recently enjoyed, through the local business Spiritual Imprints, the unique experience of searching for hag stones on the shores of Lake Ontario. The weather was rainy and quite chilly, but it was a small group of warm-hearted people and our guide lit a campfire near the water’s edge, which was roaring with waves. The misty day resulted in lovely, shiny rocks which really brought out their unique colours and markings.
