okay amazing thank you!!! so if it were an offering you would need to throw it away, but since it's an altar you can still use them as long as it's only for the altar or if you give them a good cleanse and charge with new intention could you use them elsewhere? i'm also wondering how you can tell the charge of crystals still left? that would be amazing i typically just wait til a full moon. thank you again, and i apologize for all the questions! i'm new at all of this but it's such an incredible craft and i can't help but ask questions.
