Even as a little kid I understood that gen value was heavily dependent on how the gem is cut. I have a hard time thinking anyone old enough to be employed might stumble over that.I mean, that's basically what it is. It's flavor.

Again, it causes needless complication. It also uses up needless space in the book.
I mean, if they have the means to crush it into dust and not shards, why couldn't they do it. Players have had their characters do that in my game.

The needless complication you cite comes from the result of trying to apply extreme video game logic in order to convert a generally zero weight bit of currency gem 1:1 to gem dust of equal value.
