NO! Diamond is 10 on Moh's hardness scale. The Rockwell scale characterizes the indentation hardness of materials through the depth of penetration of an indenter. The C-scale, for harder materials, uses a diamond cone and comparison of the indentations made by a 150kg weight to obtain a value expressed as "HRC". Hardness is then calculated using 100 - 500t (where t= depth of penetration). Seems to me then that If depth of penetration = 0 then HRC would be 100.
I don't know for sure (I'm a geologist not a materials engineer LOL) but I would assume since diamond is used as the indentor that, unless a diamond manages somehow to indent maybe a thin sheet of industrial diamond ? and not simply fracture it, diamond would be given the hardness of HRC100. Just my wild speculation really.

It is 10 on the Rockwell scale. The hardest known mineral.

By knowing the hardness of the metals that you are using to fabricate a structure or piece of mechanical equipment you can predict how that material is going to hold up under different temperature and loading conditions. As a general rule, materials that exceed certain hardness limits do not hold up well in low temperature applications, or in applications where they are subject to cyclic loading conditions, as they get brittle and tend to crack and rupture.

Isn't it a ten?
