The Hardest Naturally Occurring Substance on Earth


Yep - You all know from grammar school that is the diamond, which incidentally is what is used to make the stylus of our turntable cartridges.  If it is so hard, and it is going up against some fairly soft vinyl, why do we worry about poor quality LPs damaging the cartridge or stylus?  Sure, I understand the cantilever, but the actual Stylus?  The old phrase for me is "Does Not Compute".   What are your thoughts and insights?

By your reckoning agon would be absolutely full of stalkers.....
Hmm, maybe it is, never thought of that......
