Crystalarium Guide for Enhanced Mineral Production in Stardew Valley

This guide explains how to obtain and utilize the Crystalarium in Stardew Valley, a tool for efficiently producing gemstones and minerals. Note that this guide reflects the 1.6 update's changes.

Obtaining a Crystalarium

The Crystalarium crafting recipe unlocks at Mining Level 9. Required materials include:

• 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.

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 (except Prismatic Shards). Growth times vary: Quartz is fastest but least valuable; Diamonds are slowest but most profitable (5 days).

To relocate or change the gem being replicated:

1. Use an axe or pickaxe to remove the Crystalarium. A gem will drop if it's currently producing.
2. To switch gems, interact with the Crystalarium while holding the desired gem. The current gem will be ejected.

Efficiently use Crystalariums to boost profits and improve relationships with villagers who appreciate gemstones as gifts.
