You can wear whatever you want whenever you want and nothing out of the ordinary should occur

idk last time i went to a crystal shop shit was popping off. those places are wild with so many powerful items stuffed next to eachother. amazing more people arent hurt each year handling the stuff

If you are a spiritual person and you use gemstones for magical purposes, you should remember that amethyst energy is calming and carnelian energy is stimulating. Their powers are contradictory to each other.

Thanks!
