Gems are precious items of increasing rarity. They can be found in caves or obtained from meditation. They are used in the crafting of a range of items. All gems can be used to upgrade a portal or trade portal, or craft a gem pickaxe or chandelier.

All gems play a note when collected, ranging from low to high corresponding to their rarity. Each gem will also give an achievement when first obtained.
