To be honest, I'm not sure those tests would work...
The hardest scale on the Rockwell test (I'll let someone else give a link somewhere) uses a diamond to make an indent. This works for pretty much everything since diamond is the hardest material.
Until now, at least. Since diamond isn't harder than this, it wouldn't make an indent. No indent, no Rockwell reading.
