At the end of the day it's you / the practitioner who does the work, any ritual or talismans just fortify the certainty in your own sovereignty. If the crystal is indeed 'cursed' it's only a vector for the spirit, and now your / your family's fear or nervousness is what is binding it to you, legitimizing it so to speak. Banishing the previous vector isn't enough, you must fortify your own minds. Use salt-water steeped in a piece of 99.9% silver (not sterling, you can buy small cuts of jewelry or sodder wire for cheap-enough.) Anoint the tops of every doorway or threshold in the home with it as well as your forehead(s) before sleeping. During the next encounter you or they must boldly declare it is trespassing, no matter what it says or does you need only reiterate it is not welcome. You must then ignore it and move on, treat it like the pissant child it is. Each time you notice its influence again, scold it like a parent would, like it knows better (because it does, that's why these types use fear: to convince their victims they cannot fight back. The moment you do they will scatter.)
