Do crystals work for me?

[Emerald Imber]

Honestly I don't think they do. My friend's mom keeps giving me all sorts of crystals saying I need to start using them to help increase my abilities. I use them exactly as she tells me (sleeping with them, carrying them in my pocket, incorporating them into my jewelry, and using them in my everyday life) but I don't feel or see any difference in anything. She then tells me I might need to cleanse them considering that they were hers first so I cleanse them. I've run water over them, shes used sage to cleanse them, I've put some in moonlight, slept with them at the head of my bed, and (specifically pendulums) swung them above my head....... NOTHING! Yet I had one pendulum that had beads (not crystals) that represented the chakras and it worked relatively well. The mom seems to get irritated that I keep telling her they don't work because she seems very convinced they will because her spirit guides keep telling her so. I don't even know what half of the rocks she gives me are called and they are all just piling up in a little jar I have sitting on my desk. What should I do?
