Gem

Gems are a somewhat secondary currency used in Godus to purchase Belief, Wheat and Sticker Packs. They can be used to instantly construct and generate belief Abodes and Settlements, as well as instantly generate Wheat in Wheat Fields. The player begins with 20 Gems.

The Player can gain Gems by ether : Sadly you cannot gain a sufficient amount of gems in the mobile version without spending your own (or your parents'— Ask first!) hard earned money.
 * Gems can be obtained by mining the sapphire that leads to the temples.
 * (PC version) Sacrificing Followers in the Pit Of Doom (Landmark).
 * Completing Expeditions accessed from the Dock to Events.
 * Finding them in Chests, which randomly appear around the Homeworld.
 * (Mobile version) Buying them with real money.
 * (Mobile version) Getting them from rebuilding Temple of Treasures.
 * (Mobile version) Watching advertisements.

An unfixable glitch exists that prevents the player from accumulating any gems. When the player is first introduced to gems, they are given 20 to start with. If you don't receive the 20 gems (and you are at the point where you are prompted to use them) you must restart to try again with a new save file.
