[Him]

I guess, but the only gems that get last names have two names for the gem. Like Rose Quartz and Lapis lazuli. Maybe instead of just Agate you can use a specific type of Agate. Like Blue Lace Agate, Moss Agate, Eye Agate.

Also don't forget as a crystal gem she has the other powers like Bubbling, horogram, form shift, and gemfusion. Don't forget to include those and for thos other powers you have for her, can you choose a main one for a unique ability? Like one specific to her gem? Like Garnet can swim in Lava, Amethyst can eat clouds, and Pearl can manipulate sand. And then my oc Moonstone has the unique ability to heal emotions, so someone going beserk she can calm them and anyone who's depressed she can heal that.
