This piece is crystal and freshwater pearl. It was created by a sorceress that belonged to a group called the Sisters of Caduceus. The group functions like a mystery school, except they are very choosey about who gets to be in the group, starting with the fact that they are all female. This doesn't mean a male can't use this piece, it just means that the only way a male will ever get their hands on one of their pieces is through some sort of means like this and since their pieces are rare to begin with, we are going to go ahead and say this is your chance.
When wearing this piece you will be able to write down anything you want and it will become a spell. Want wealth? Love? Spiritual Healing? Revenge? Something else? It's all good. This piece will definitely get it done for you. As you can see there is a contrast between light and dark beads. This represents the fact that this piece is dual magic and can be used for either light or dark intents. It depends on your intentions when writing the spell what kind of magic this piece will use to cast it.
