For those of you who work with crystals, from everything I've read and been reading crystals always have positive effects on those who use them (love, protection, balance, etc...). Considering the universe and Wicca are comprised of balance, it seems that there would be some crystals that would effect people negatively.
From what I've read, different crystals can have different effects for different people as well. But, I'm talking more generally...
What are your thoughts on this??
