Approx 37.8 Rockwell "c" scale
Diamond is more than 1000 times harder than quartz, which is in the 80 range in the Rockwell C. Diamond cannot be measured on the Rockwell C scale. A diamond pyramid is actually used in the Rockwell C test, which would be inconclusive.

Rockwell hardness
RC stands for Rockwell Hardness C scale; the different letters A,B,C etc. are based on different loads and indenters for measurement. C scale is typical for steels, while B scale is typical for aluminum. There are conversion tables for these if needed.
The Mohs scale of mineral hardness is named after Friedrich Mohs, who developed it. The Rockwell scale of metal hardness is named after Hugh and Stanley Rockwell, who created the machine that measures it. Hugh and Stanley Rockwell aren't directly related to each other. The Shore Durometer scale for measuring the hardness of elastomeric materials like rubber is named after Albert Shore, who invented the measuring device called the durometer.

The element neon has no hardness on either moh's hardness scale or rockwell scale unless it is frozen. These scales measure only solids.
Rc is an abbreviation for the Rockwell Hardness Scale, used to determine the harness of materials.
It can't be accurately converted.The softest metal on the C scale gets a 1 rating.That 1 rating is the equivalent of 82 on the B scale, which is the Rockwell scale used for copper.Copper and all it's alloys are down around the 40 range of the B scale.And you can't assume that a B scale 40 is half of a C scale 1, either. Since the tests use different metal ball sizes, it's an issue of being an unequal scale.
You dont. Minimum C is about maximum B. And the indentation is different. Even if you could convert it, the results would not be accurate.
