Magi Gems
Edit

Arianna with a siguel
People that work for the capital have pointed gems, while civilians like Arianna have round gems.
It is implied that there is some skill involved in using magi gems, as it is implied that some mages are more powerful than others. It is also stated that no one (with an exception of Vector) is able to use magic without one.[2]
When in use, a magi gem will produce a magic circle or siguel. It is the same color as the gem, and has a pattern in the middle. Most humans do not use siguels.
