However, I do think that some crystals will cancel each other out because of the different frequencies you’re trying to entrain with.
For example Carnelian is a stone of energy ~ it’s a stone that really helps to boost energy.
Another stone is Blue Lace Agate. Blue lace agate does the exact opposite of what carnelian does ~ it calms energy down.
So if you were to put these 2 together in a combination of any kind, like in a crystal grid, it would be really confusing!
Do you really want to calm things down or do you want to boost the energy? This combination of crystals would cancel each other out.
