The player can see that a builder builds the Gem Maker and upgrades it if they observe closely, and it has no workers or materials that are produced. It is connected to a harbor side-quest, which is to deliver 200 gold to the harbor to fund them so they are able to sell more gems at once.
- It presumerably costs 200 gold to build and to upgrade.
- If the player uses cheats to play as the harbor faction, the information screen for the building shows that there are no earnings, workers, materials, needs, or decorations.
