Next comic will be Friday
This is a parody, and is not endorsed by Cartoon Network, or the people who make Steven Universe. This is purely for fun.
Got done in about two days.
It is very good.

The irony of what garnet said.....
Not to nitpick, but we know several harder materials than corundum, including boron, silicon carbide, and titanium carbide.

They did specify minerals, but that only excludes TiCarbide, as I don't think that occurs naturally (or at least not in big enough chunks). Chalk it up to Marceline not knowing her geology/earth science.
I'm really enjoying this comic though, it's hilarious!
