Did You Know? In the olde days Hagstones were popular charms to use around the home for protection? (photo shows the one we have in our home along with an iron key.) A hagstone displays a naturally worn hole from nature. Once as popular as using the lucky horseshoe to protect against negative influences and attract good, people would also wear hagstones around the neck. They were popular to hang in the barn too on rural properties, keeping away the naughty fairy folk from the horses through the night hours!
