The '''Crystalarium''' will replicate any inserted [[Minerals#Gems|Gem]], [[Minerals#Foraged Minerals|Foraged Mineral]], or [[Minerals#Geode Minerals|Geode Mineral]]s. It is obtained through [[Crafting]], donating 50 [[Minerals]] to the [[Museum]], as a reward for completing the {{Bundle|25000|16|y}}, and may occasionally be found in a [[Skull Cavern#Treasure Rooms|treasure room]] in the Skull Cavern.

The '''Crystalarium''' will replicate any inserted [[Minerals#Gems|Gem]], [[Minerals#Foraged Minerals|Foraged Mineral]], or [[Minerals#Geode Minerals|Geode Mineral]]. It can [[Crafting|crafted]] or found in a [[Skull Cavern#Treasure Rooms|treasure room]] in the [[Skull Cavern]]. Note that Crystalariums cannot replicate [[Prismatic Shard]]s. The functions of the Crystalarium are explained in '[[Lost Books#Technology Report|Technology Report]]''.

Once an item is inserted, it will replicate that item an infinite number of times. Once a gem or mineral has been inserted into the Crystalarium, it can be retrieved at any time by replacing it with another replicatable item, or by removing the Crystalarium with a tool. Note that it is not possible to duplicate [[Prismatic Shard]]s - in the [[Museum]] there is a book that explains this inability, stating: "For some reason, the EMF from the shard interacts negatively with the crystalarium")

* The most profitable gem to replicate is the [[Diamond]], yielding a profit of {{price|150}} 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 [[Broken Glasses]] and [[Broken_CD]]s, without needing coal.

**Five Quartz can be traded at the [[Desert Trader]] for 1 [[Bomb]], making the replication of Quartz in Crystalariums a more efficient method of obtaining Bombs than purchasing them from the [[Dwarf]]'s shop for {{price|600}} each.

* The Crystalarium can replicate [[Jade]] for trading with the [[Desert Trader]] for [[Staircase]]s on [[Days of the Week#Sunday|Sundays]]. This can save countless hours gathering stone.

* When changing the gem in a Crystalarium, first break the Crystalarium to get the seeded gem back (otherwise the gem in the Crystalarium will be lost and replaced with the new gem). Then place it down again and insert the new gem.
