Formation & Geological History

Formed through physical and chemical weathering. In many cases, these stones are limestone or flint where a softer fossil inclusion (like a briozoan or sea urchin part) or a weak mineral pocket has eroded away due to the action of running water or waves.

Uses & Applications

Primarily used as a lucky charm, in folk magic (for protection), as decorative garden stones, or in jewelry.

Geological Facts

In European folklore, these are also known as Adder Stones, Hole-ey Stones, or Witch Stones. They were traditionally hung on doors or around the necks of livestock to ward off evil spirits and nightmares.

Field Identification & Locations

Found on beaches or in riverbeds. Identify by looking for a hole that has been clearly bored through naturally by water action rather than by human tools. Often found in areas with high limestone or flint deposits.
