Resource Overview History
Diamonds are one of the 31 rare resources. They appear as a bunch of their namesake diamond crystals.

Like with all rare resources on land, Diamonds can be gathered by sending a Merchant from the Market to the resource location. Diamonds provide the following benefits:

  • +20 Wealth Wealth gather rate
  • Raises Commerce Limit Commerce Limit by +10%
    • The 10% Commerce Limit Commerce Limit increase are based on the Commerce Limit Commerce Limit from the current Commerce Commerce research level. For example, if you have researched Commerce Commerce 4 (Mercantilism), the Commerce Limit Commerce Limit would be 260. Having Diamonds connected would raise the limit by 26 to 286.
    • Commerce Limit Commerce Limit bonuses given from Wonders (like the +50 Timber Timber/Wealth Wealth from the Colossus) are not taken into account when calculating the 10% (thus, in the above example the Colossus would simply increase the limits for Timber Timber and Wealth Wealth from 286 to 336).

The gather rate of rare resources can be increased in various ways, as described in the main article.

If Diamonds are available nearby the starting location, they should be connected early, as they provide a fair boost to the otherwise weak initial Wealth Wealth production.
