The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz

the mohs hardness scale
It is about 2.5 in the Mohs Hardness Scale.
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.

Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
it is 6 1/2 in the mohs hardness scale
I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
