Natural Lodestones can be carried as an all purpose amulet also for protection against any form of evil. That is why they should be carried in pairs. One to take away the evil and bad luck, the other one to draw the good luck your way. Lodestones need to be fed once a week with magnetic sand. They can be carried in a red flannel bag, in which other good luck charms can be added. Size approximately 1 1/2 in. to 2in. long and weight about 2oz.
