This guide details how to obtain and utilize the Crystalarium in Stardew Valley, a valuable tool for gemstone farming. The 1.6 update introduced subtle changes to its functionality, which are included here.
Obtaining a Crystalarium
The Crystalarium recipe unlocks at Mining Skill Level 9. Crafting requires:
- 99 Stone: Easily obtained by breaking rocks.
- 5 Gold Bars: Smelt Gold Ore (found at mine levels 80 and below) using Coal in a Furnace.
- 2 Iridium Bars: Smelt Iridium Ore (found in Skull Cavern or from the Statue of Perfection) using Coal in a Furnace.
- 1 Battery Pack: Obtained by placing a Lightning Rod outside during a thunderstorm.
Alternatively, acquire a Crystalarium by:
- Completing the 25,000g Community Center bundle (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 strategically using the Crystalarium, players can significantly increase their gemstone profits and enhance their relationships with Pelican Town's residents.
