      I don’t know-that’s a question for a chemist (or google).

      That hardest mineral is a Diamond. Its a 10 on the Moh’s hardness scale. Though there may be some man made alloys that are harder. Tungston is pretty hard.

      Just looked it up, yep it’s diamond! Though borium helps make hard material apparently. Thanks to you learned something new today!

      Diamond is the hardest natural substance. We can add some elements (like tungsten) to them to artificially make them even stronger.

      It’s so cool that people can make things even harder than diamond!
