The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)
Diamond is the hardest mineral and ranked as number '10' according to the Mohs hardness scale.The Mohs scale minerals from softest to hardest:1. Talc (softest)2. Gypsum3. Calcite4. Fluorite5. Apatite6. Feldspar7. Quartz8. Topaz9. Corundum10. Diamond (hardest)
Diamond, with a hardness of 10 on the Mohs scale.
The hardest mineral is diamond, and the softest mineral is talc.
The order of minerals from softest to hardest is: talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum, and diamond. This scale is known as the Mohs scale of mineral hardness.
The hardest mineral is diamond, which has a hardness of 10 on the Mohs scale.
On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)

A diamond and talc
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.
Hardness
The order of minerals from softest to hardest is: talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum, and diamond. This scale is known as the Mohs scale of mineral hardness.
Diamond is the hardest mineral, scoring a perfect 10 on the Mohs scale of mineral hardness.
