That reminds me I need to set up the whole Jewelers crafting web. So many aspects of the game to do. Seems like I have too much on my plate. I will hopefully get to it eventually, since I did have a plan for it using the goods system and the "smithing" buildings. Basically the gem mines would make Good (Raw Gems) and then it would unlock a Gem Cutter which would make Good (Cut Gems). Meanwhile the smithing buildings like the Goldsmith or Silversmith would produce Good (Precious Metals) which along with Good (Cut Gems) would unlock the Jeweler's. In short ..
Fake Resource -> Processing -> Jeweler's
Doesn't that sequence mean you'd be out of luck if you didn't have gems? i.e. - there is no jewlery that doesn't involve gems, so just gold, or semi-precious stones etc. are not good enough ever?
