Cat’s Eye’s are often carried or worn for protection to ward off the evil eye. This shell is an operculum or foot-closure of a sea-snail to protect it in the ocean. It is widely used in European and the Middle East for protection due to its uncanny resemblance to an eye. May be worked with in any spell for protections, talismans and mojos.
(The variety we have found is apparently quite large in comparison to what is often found in other shops. Probably close to the size of a silver dollar if not a tad bigger)
