Holey Stones are rocks that have a naturally-formed hole through them. Some cultures consider these to be good luck. Believers in magick and ancient religions (animists, pagans and wiccans) consider holey stones to have powerful positive energies. In these belief systems, one can perceive the Fey realm by looking through the hole. Others believe that Holey Stones have healing powers, psychic energies, or bestow protection upon the bearer.
Holey stones have been called many things - men-an-tol, an-cloc consanta, crick stones, fairy stones, hag stones and Odin stones. Some modern Holey Stones have been artifically drilled out.
This particular Holey Stone is 100% natural, undrilled and unaltered. It has four holes that go completely through. The shape of the stone is very interesting. The holes in this case were caused by a marine organism called a "clam bore" which slowly creates a hole for itself in host rock. When the clam bore dies, the hole remains.
You get the actual stone shown in the photos. The black centimeter cube is shown for scale and is not included.
