The Crystalarium will replicate any inserted Gem, Foraged Mineral, or Geode Mineral except Prismatic Shards. (In the Museum there is a book that states: "For some reason, the EMF from the shard interacts negatively with the crystalarium"). Once inserted, it will replicate that item an infinite number of times. Once a gem or mineral has been inserted into the Crystalarium it cannot be removed, only replaced with another. The original item is lost and so it is best to let it finish at least once to avoid loss.

It is obtained through Crafting, donating 50 Minerals to the Museum, or as a reward for completing the Bundle Purple.png 25,000 Bundle in the Vault.

  • The most profitable gem to replicate is the Diamond, yielding a profit of Gold.png150g per day if harvested as soon as it is ready (five days). At this rate, you can recover the base monetary value of the materials used in crafting the Crystalarium in about 32 days (not including a Diamond used to seed it, nor any increase in the value of the crafting materials due to profession bonuses).
  • Only 7 hours is required to replicate Quartz, the shortest time span for any mineral. While the Crystalarium is thus an efficient source of Quartz for making Refined Quartz, Quartz is found abundantly during mining and making Refined Quartz still requires Coal for smelting. Refined Quartz can also be produced directly in a Recycling Machine from some types of fishing forage, without coal.
