got my first set of crystals saturday. they came with a huge headache that i woke up with. once i got to the mail later in the evening i found the bad one put it in seat salt to cleans. i dont ever really do things like this but ive been so aware of the energies i pick up lately that it just felt like the right thing to do. idk im just going with it. i bought them to make some necklaces n such. i love em i have one that is 7 faced which i great i hear. that one picked me out i think.
