Black Onyx and Discolouration?
I'm type one diabetic and use rubbing alcohol alcohol swabs to clean injection sites for my insulin. I was wearing my onyx ring, and I suppose as I was preparing to use insulin, the swab touched the ring.. there's a small patch that's now discolored; I was wondering if that disrupts its natural energy or magikal properties? I've taken it off until I can be sure.
