This Stardew Valley guide explains how to obtain and use the Crystalarium, a valuable tool for efficiently producing gemstones and minerals.
Obtaining a Crystalarium
The Crystalarium recipe is unlocked at Mining Level 9. Crafting requires:
- 99 Stone: Easily obtained by breaking rocks.
- 5 Gold Bars: Smelt Gold Ore (found at mine levels 1-80) using a Furnace and Coal.
- 2 Iridium Bars: Smelt Iridium Ore (found in Skull Cavern or from the Statue of Perfection) using a Furnace and Coal.
- 1 Battery Pack: Obtained by placing a Lightning Rod outside during a thunderstorm.
Alternatively, you can obtain a Crystalarium by:
- Completing the 25,000g bundle in the Community Center's Vault.
- Donating at least 50 minerals to the Museum.
Using the Crystalarium
Place the Crystalarium anywhere (indoors or outdoors). Popular locations include the Quarry for mass production.
The Crystalarium replicates any mineral or gemstone except Prismatic Shards. Quartz has the shortest growth time but low value. Diamonds have the longest (5 days) but highest value.
To move a Crystalarium, hit it with an axe or pickaxe. Any gem currently being replicated will drop. To change the gem type, simply interact with the Crystalarium while holding the desired gem; the old gem will be ejected.
By using the Crystalarium, players can significantly increase their gemstone profits and create valuable gifts for Pelican Town's residents. Note that the 1.6 update subtly altered Crystalarium mechanics regarding movement and gem swapping. This guide reflects the latest game version.
