Gemcutters' Guild Hall is a Dwarfs resource building in Total War: Warhammer. The Gemcutters' Guild is rich, by the very nature of the commodity in which it deals.
Background
Men or Elves visiting the Gemcutters' Guild would see a hall gleaming with gems inserted in the walls at geometric points, but would probably still see something largely functional. To other Dwarfs, the hall is gaudy and a crude display of the Guild's wealth, used to remind other institutions and even the Royal Clans of the power they wield.
