On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
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.

No. Hardness is measured on the Mohs Scale, named after German Friedrich Mohs. On this scale Talc (the softest) measures 1, while Diamond (the hardest) measures 10. Glass has a Mohs' scale hardness of around 5.5, so anything above that will have the ability to scratch glass. For example, quartz (Mohs 7), hardened steel (Mohs 8), corundum (rubies and sapphires, Mohs 9),or diamond (Mohs 10). The Mohs scale is purely an ordinal scale, expressing relative hardness in a simplistic way. Carborundum (Mohs 9) is twice as hard as Topaz (Mohs 8), but diamond (Mohs 10) is four times harder than arborundum.
It is dia mond . . . diamond. On the scale from 1 to 10, diamond is the hardest at 10.
The field test for diamond is 'extreme hardness'. Diamond is rated as 10 on the Mohs Scale, 10 being the hardest. Diamond is the hardest mineral on earth.
The hardness of diamond is measured on the Mohs Scale, and diamond is the hardest mineral on the scale, ranked at 10.
Diamond is the hardest known mineral on earth, topping the Mohs Scale of hardness at 10.
