Corundum

And there she is, the One-Punch-Gem, Corundum!
I have a tiny headcanon. Do you guys knew rubies and sapphires are actually the same stone? We only call them differently because of their colors. But rubies and sapphires are both corundum!
And my headcanon is that: when Homeworld tries to make a Ruby or a Sapphire, there is a tiny chance that its color drains a bit and a Corundum pops out instead. Corundums are heavy hitters, much better soldiers than Rubies, however they don't have the foresight of a Sapphire and when what was supposed to be a Sapphire "devolves" into a Corundum it tends to disappoint the Diamonds a bit. Okay a lot.

This here Corundum is a "good" one, meaning it was supposed to be a Ruby at first. Her weapons are brass knuckles! And trust me you don't want to be at the end of her punch. Even without the brass knuckles, she could give a Gem a big crack or shatter your skull.
Don't be fooled, despite being buff, she's not that tall. But what she lacks in height she makes up for in sheer force. She's small, but swole. She's smwol.


Corundum belongs to me.
