This is what you need to know about how to get your own Crystalarium and what the best item is to put in it.

How to Make and Use a Crystalarium

There are a few different ways you are able to get a Crystalarium in this farming sim title. The first is by donating 50 minerals in total to the Museum, which is one of the most straightforward ways to get one. You can also get this item by finishing the 25,000 Vault Bundle. Finally, it is sometimes found in Skull Cavern Treasure Rooms.

How the Crystalarium works is you are able to put various minerals and gemstones into it. The goal is to duplicate that particular item and have another version ready to go. Each item takes a different amount of time to craft a new version, but the machine will continuously make infinite copies of that particular gem until you stop it.

Best Item to Put in the Stardew Valley Crystalarium

There is a particular best item to put into the Stardew Valley Crystalarium if you want to make the most profit possible. At the end of the day, personal preference matters a lot. However, if you just care about making that sweet money, the item you should leave in the Crystalarium is Diamond.

This is because Diamond gives you the most bang for your buck. Yes, it takes five days in-game to craft a duplicate. However, it sells for 750g each, which nets you around 150g per day if you divide it up by the time it takes. This is considerably more profitable than the next best items, such as Star Shards, Helvite, Emerald, and Jade.

Stardew Valley is available right now for Android, iOS, Nintendo Switch, PS4, Xbox One, and PC.
