Stardew Valley: How To Get & Use The Crystalarium

This guide explains 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 addressed here.

Obtaining a Crystalarium

The Crystalarium recipe unlocks at Mining Level 9. Crafting requires:

• 99 Stone
• 5 Gold Bars
• 2 Iridium Bars
• 1 Battery Pack

Alternatively, you can obtain a Crystalarium by:

• Completing the 25,000g Community Center bundle.
• Donating 50 minerals to the museum.

Using the Crystalarium

Place the Crystalarium anywhere – indoors or outdoors. Popular locations include the Quarry for large-scale production.

The Crystalarium replicates any gemstone or mineral (except Prismatic Shards). Quartz has the shortest growth time but low value. Diamonds offer the highest profit despite a 5-day growth cycle.

To relocate or change the gem inside:

• Use an axe or pickaxe to retrieve the Crystalarium. A currently-growing gem will drop.
• To switch gems, simply interact with the Crystalarium while holding the desired gem. The existing gem will be ejected.

Efficiently using Crystalariums significantly boosts profits and provides valuable gifts for Pelican Town's residents. Strategic placement and gem selection maximize returns.
