A talisman is an object, sometimes engraved, inscribed, or marked with a symbol of some sort, believed to have magical properties (likely made with that intent, or imbued through some process). Typically, it is an item which is worn or carried for the purpose it was made to fulfill, such as an amulet charged with psychic protection, or something as simple as a worry stone.
What do you mean by wanting to "apply" a talisman to something?
If you thought about an object which could remind you of some person or some place, it is simply called medallion. And it needs no magic except soul) Still, it is a hard thing to get certainty in whether you have soul or you don't) And it is especially hard for meX)
