It is the hardest material. It's just that the word "hardness" in this context is often misinterpreted. Hardness is just one material property. There are also other properties that determine in which ways the material can be broken and how easily it can be broken.

Diamond is very easy to break. If you ever get diamond jewelry and someone makes a bet that they can break it, don't ever bet against them.
