Here is a little explanation of all the gems in Steven Universe. Including my rating on the character. Be free to recommend a gem I didn't add. But don't be too mad if I don't add them. WARNING. There are major spoilers of the whole show. Unless you want spoilers or have finished the franchise, you best avoid this project. P.S. Sorry I haven't posted in so long...
Cartoon Network for the show. Steven Universe Wiki for most of the images. @firekitten5 for the audio.
