Using the Crystalarium

Crystalarium in Use

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

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

To relocate or change the gem type:

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

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