Diamonds serve as a unique currency that allows you to speed up your progress and instantly purchase items and resources that you lack. There are a few ways to get them:
  1. Increase your level
  2. Complete missions
  3. Find chests and treasure piles hidden throughout the game world
  4. Receive in chests obtained by filling orders on the Board (they are awarded as the meter at the bottom of the board fills up, and when you complete particularly difficult orders)
  5. Explore the crevice on your home island – you can sometimes find diamonds there (unlock by completing missions on the home island)
  6. Purchase from the bank or take advantage of limited-time offers
