Silver to fend off possession and possessed. Diamonds to trap demonic energies. Gold to attract wealth - money loves warm and charged places. Let me add that this reshapes and diminishes your aura as well - you don't need any of this if you walk in authenticity. You are untouchable. Your gaze alone dispels demons. No one can talk to me, face to face, and lie. Through my eyes stares the One that Sees All. No material is ever "just for sentimental value". Everything has a function. When you understand the nature of a thing - you understand its value.
