Before anyone says anything, I want to clarify this; I'm young, yes, and I have somewhat undesirable intentions, yes, but I've been told before, and I'm just looking for some advice.

I've recently started dabbling with the idea of taking pieces of jewellery and binding them so as to have certain effects when they're worn

Each effect would be only very subtle, but they each relate to manipulating others.
Examples:

A red ring to inspire chaos around the wearer
A black ring to draw lustful intentions about the wearer
A white ring to invoke a sense of trust around the wearer

How would you suggest I go about creating an appropriate ritual to enchant these rings?
What would I use in the spells, what ingredients, what time of month, what symbols and incantations? Some advice, would be lovely.
