The in-game stone icon

Stone is one of the primary resources of your Civ. It is used to build Buildings for you Civ in conjunction with wood and sometimes a tertiary resource. The Trader may also request stone in exchange for gold.

While gathering stone, either automatically or by manual clicking with a base chance of 10%, ore may also be gained.
