Well, it should be since according to many fringe authors granite can only be scratched with diamond tipped tools. If that is the case since a piece of quartz stuck on the end of a cocktail toothpick can scratch quartz (the hardest mineral in granite)..... that means to a believer that piece of quartz must therefor be diamond. But that really should not be that surprising because quartz is only about 11% the indentation hardness of diamond and just like diamond can scratch diamond (thus wedding rings), quartz can scratch quartz too, and there are a lot of minerals harder than quartz that must be diamond also. I know it's silly, but that's the true nature of fringisms. The problem with this fringism is that no matter how clearly one demonstrates its lack of any validity it's just to good for them to let it go........
As for perfection..... apparently no one bothered to measure this one, at least I hope not, but I would not be surprised if that was actually the case. Let me guess the vibro-lath was off balance as the block was spin-polished......
