The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)
The scale used to find a mineral's hardness is called the Mohs scale. It ranges from 1 (softest) to 10 (hardest), with each mineral tested against known reference minerals to determine where it falls on the scale based on its ability to scratch or be scratched by the reference minerals.

On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
The hardest mineral is diamond, and the softest mineral is talc.
10 is the hardest mineral on the scale. Since Mohs understood this to be the diamond (based on tests scratching different minerals) the diamond was designated a 10.
