This mod makes them significantly less
worthless.
The value of all gems is multiplied by a certain amount based on quality. Flawed gems are worth 3 times as much as normal, Standard are worth 5 times as much, and flawless are worth 10 times as much!
That 100 gold Flawless Diamond is now worth 1000 gold! There's now some actual worth to all that shininess!
There's also an optional file called Expensive Nuggets that makes silver and gold nuggets worth more.
Their value has been multiplied by 5.
You can also get the old 1.0 version if you want. It multiplies the worth of all gems by 10, which is frankly a bit too much, but I left it as an option.
