Ok I started to read but even without reading past the first sentence, please break up your paragraphs. There's also (in my opinion, this isn't entirley objective) not enough characterization or worldbuilding.
EDIT:
Ok, now I have read it. This is decent. I still have the problem where you should break up the sentences, but that's not a mojor issue unless you want to publish a high-effort story filled with big blocky paragraphs.
I like the setup, it seems good, but I think you should make this longer. Not only should this moment be longer, stack on the importance of this decision (and if it's not important, don't put so much weight on it) and even then I think it'd be better if you had at least some snippets before this.
I'm suggesting this so the reader can get a feel of the mc's personality, get more information on other important characters already in the story, to build up the world, for more a more vivid moment, ect. I also think you should change how the gems work a bit and/or make them more of a side thing because as is it seems only the flarian has risk, and you mentioning the mc thinks the grizmald is bland and that the azulire was recommended by the librarian Alfred makes one gem seem highly logical.
As for continuing the story, you seem to have a basis here but it's hard to give advice when this snippet is all you've given us to work with. Going to your story, it seems you haven't written anything down yet but maybe that's just you waiting for more in depth advice.
Because it's a priest telling this to the noble, I asume it probably has ties to whatever religion this land has. And I'm a tad confused, does your story work differently than most fantasies with nobles? Er, that's bad sorry. My question is, usually nobles don't have "jobs" exactly so I'm a bit confused. Unless I'm just stupid which really isn't that surprising if that's the case.
So from what I can tell, choosing the grizmald is a garentee that you'll end up a druid? Why is this? And if the full power of a flarian is hardly ever used, than why is it so valuable? Because it's a gem? Maybe it's really pretty? If you say because you can sell it for a lot of money to people who will use it, than it's not used less but by more common folk. Or maybe someone else in high social standing hording it for their benifit, or the kingdom/kingdom's rulers for a war or something.
And because you were wondering, I think it could be really interesting to a reader! Almost any idea could, it just heavily depends on the reader's attention span and acceptance and the writer's quality. Most readers on this site are pretty acceptant, and have no problem with a variety of stories. Like, Eternal is one of the most popular stories on this site if you want an idea of what kind of stuff these people are ok with so if your story is well written I'm sure it'll be fine.
I would try to give more advice, but there's really not a lot to go off of. Have a good day, and good luck with your story. :D
TL;DR: make it longer, don't info dump (spread it out), put more or less importance on the gems, and add more characterization and worldbuilding to start. I highly suggest you read my whole post when you can though, this short bit isn't as helpful.
Oh, also, you may want to look at this. There are also a ton of articles helpful for writing.
