I just realized, I don't know the first thing about gemstones.

So instead of trying to educate yourself or learn something you could find on google, you just sit around being dumb?

Oh, whoops.

*Is there a good place to read up on gemstones and relative value.

Don't know online ones offhand, learned from physical books. Going in from scratch, know that gems can get complicated fast.

Colour, cut, clarity, and carat are a good place to start with diamonds. Remember than minerals, like jade are also gems. A well-polished piece made by a skilled jeweler can go for higher than a more "valuable," rock cut badly. Many times, colour is caused by characteristic impurities, leading to different levels of colour, even if the gems would be classified the same way, chemically speaking.

Rule of thumb, the rarer and more lustrous something is in your setting, the more valuable; especially if you want to start using economic shenanigans.

That should be enough searchable terms for you to start reading. Time to go digging, enjoy your shiny rocks.

Almost forgot. Since these things are probably getting pulled out of the ground, setting and geography matter more. Go check Dwarf Fort's wiki, DF is good at geology.

Now go read. Too much to cover in a board dedicated to Chinese paperback cooking comics.

They are truly outrageous, for starters.
