GK is worth a whole 2 cents?
Blimey talk about inflation!

Speaking of world’s hardest substance! I ought to clunk your heads together.

I think it is more to do with the actual pressure seen at the stylus while playing vinyl that wears the diamond out.
And as for accidental damage it is not the diamond itself we often damage as that would be VERY difficult but rather the cantilever as you rightly say AND the adhesion of diamond to said cantilever..
That is what the klutz amongst us usually end up ruining, just knocking the diamond off completely.
Not much fun when you drop what you thought was the needle just to see the arm go skidding right across the record.......

Uber, you’re a genius at stating the obvious. 🤗 Slow day at the beach? 🏄🏻‍♂️
