Diamond, the hardest naturallly occurring mineral currently known.
Diamond is the only mineral with a hardness of 10 on the Mohs scale.
Diamond is the only mineral with a hardness of 10 on the Mohs scale of mineral hardness, and as such, it is the hardest mineral on the scale.
The only mineral with hardness of 10 is a diamond. :)
A diamond. It's the only 10.

Diamond, with a hardness of 10 on the Mohs scale.
Galena is listed at 2.5 on the Mohs scale of mineral hardness.
Tals, a mineral, has a hardness of 1 on the Mohs scale of relative mineral hardness, a 1 being the one able to be scratched by the remaining nine minerals. It's soft.
Talc is the mineral with a hardness of 1 on the Mohs scale.
Is a mineral's ability to resist being scratched, and is defined by its location on the numerical Mohs scale of mineral hardness by a designation of a number between 1 and 10. See the related link on Mohs hardness.
On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
Diamond, with a hardness of 10 on the Mohs scale.
It's called the Mohs scale of mineral hardness.
Hardest - Diamond Hardness - 10
Galena is listed at 2.5 on the Mohs scale of mineral hardness.
Hardest - Diamond Hardness - 10
The diamond is the hardest know mineral that can scratch all other substances. It is also rated 10 in the Mohs hardness scale.
Tals, a mineral, has a hardness of 1 on the Mohs scale of relative mineral hardness, a 1 being the one able to be scratched by the remaining nine minerals. It's soft.
The hardness of diamond is measured on the Mohs Scale, and diamond is the hardest mineral on the scale, ranked 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.
Scientists use the hardness test, and more specifically Mohs Hardness Scale, named after a Freidrich Mohs, a German mineralogist. Mohs Hardness Scale test can scale from 1 to 10, where 1 is softest and 10 is hardest.
It is dia mond . . . diamond. On the scale from 1 to 10, diamond is the hardest at 10.
