There are as many possibilities as there are individuals who might be looking to wear a Spirit Carrier crystal amulet!
No two amulets ever end up exactly the same - similar stone combinations perhaps or resembling each other, but never totally identical. Each of you is an individual, with your own specific energy signature. When I work, I'm constantly tuning into the purpose that any crystal amulet will be for.
So in that way, each crystal amulet is specifically made for the one who will be wearing it.
