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

*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, the base monetary value of the materials used in crafting the Crystalarium can be recovered 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).

**Diamonds can also be traded with the [[Desert Trader]] for the [[Triple Shot Espresso|triple shot espresso]].

**[[Diamond]]s are also either liked or loved by all villagers, making the replication of Diamonds useful for gift-giving purposes.

*[[Earth Crystal]]s can be replicated in about 13 in-game hours, providing two nearly universally liked gifts each day. This is more efficient than replicating diamonds and either gifting them or selling them for [[Salad]], which is the cheapest universally liked item that can be bought.

*Only 7 in-game 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]]. The staircases can then either be used or inserted into a [[Deconstructor]] to produce 99 [[stone]]. This can save countless hours gathering stone.

*The Crystalarium can replicate [[Ruby|Rubies]] for trading with the [[Desert Trader]] for [[Spicy Eel]]s. The Spicy Eels can then be eaten to increase [[luck]] and [[Speed#Player Speed|player speed]]. This can also save time from [[cooking]] them with [[eel]]s and [[Hot Pepper|hot peppers]].
