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?

geoffkait, ''ability to hear when the stylus is worn?'' There are many
who are not able to see if the stylus is worn even with their new
(expensive) microscoope. I always asked Axel and he always
advised an new one (grin).

Sphere?    Block?     Never been that normal.      Perhaps: a rhombohedral ellipsoid!

There are some folks on here who polish their diamond upon hearing the difference. Diamond-Brite---on a website near you.
