Stardew Valley: A Comprehensive Guide to Crystalariums

Stardew Valley offers more than farming; players strive for profit, and gemstones are valuable assets beyond their aesthetic appeal. They're useful in crafting and make excellent gifts. However, mining for rare gemstones can be time-consuming. This is where the Crystalarium proves invaluable, allowing players to multiply gemstones and minerals. This guide covers its acquisition and use, updated for the 1.6 update.

Obtaining a Crystalarium

To craft a Crystalarium, players need level 9 Mining skill. The required materials are:

• 99 Stone: Easily obtained by breaking rocks on the farm or in the Mines.
• 5 Gold Bars: Smelt Gold Ore (found at mine levels 80 and below) using a Furnace and Coal.
• 2 Iridium Bars: Mine Iridium in Skull Cavern or obtain it daily from the Statue of Perfection. Smelt Iridium Ore using a Furnace and Coal.
• 1 Battery Pack: Obtain these by placing Lightning Rods outside during thunderstorms.

Alternative Acquisition Methods:

• Community Center Bundle: Complete the 25,000g bundle in the Vault.
• Museum Donation: Donate at least 50 minerals (gemstones or geodes) to the Museum.

Using the Crystalarium

Place the Crystalarium anywhere – indoors or outdoors. The Quarry is a popular location for multiple Crystalariums.

The Crystalarium replicates any mineral or gemstone (excluding Prismatic Shards). Quartz has the shortest growth time but low value. Diamonds have the longest (5 days) but highest value.

To remove a Crystalarium, hit it with an axe or pickaxe. If active, the replicated gem will drop. To change the gem, simply interact with the Crystalarium while holding the desired gem; the current gem will be ejected.

By utilizing Crystalariums, players can significantly increase their profits and enhance their relationships with Pelican Town's residents through gifting valuable gems.
