Do you want to replicate gems and make more gold in Stardew Valley? Have you thought of gifting a villager, but you don’t have the priced mineral? A Crystalarium can help you, and this guide will teach you how to find or craft one in no time!
Exploring the caves to forage or dig valuable rocks is enjoyable despite the risk. Not only will you scale your mining skills, but you can also gather valuables below the surface. But what if there’s a long-term solution for this hobby without risking your head?
If there’s a mineral-copying machine in the game, Crystalarium would be your handy tool. Gem Sea’s brilliant minds give birth to the luxurious equipment that even copies the most expensive Diamonds.
In this beginner’s guide, you’ll learn everything about the machine. Getting one can be intimidating as well. That’s why we’ll give you valuable tips to increase your chance of having the item in early-game.
Here’s the magic about a Crystalarium: it can replicate a single gem endlessly. If you load Quartz, inserting another is unnecessary as you only have to collect its copies. The process will continue as long as you don’t break the machine or insert another gem or mineral.
To make a Crystalarium, you need to reach Level 9 in Mining to unlock the crafting recipe. Afterward, you’ll need 99 pieces of stone, five gold bars, two iridium bars, and a battery pack for a single machine.
How to Get a Crystalarium Fast
Although the Crystalarium gives you an edge for gift-giving and profiting, getting one can be tricky. Instead, you may want to consider these easy and proven methods:
Donate 50 Minerals to the Museum
The local mines are home to many riches you won’t see in the ground. Alongside ores and stones, you can dig minerals and gems that Gunther would love to add to his collection.
Twelve foraged minerals and gems in total are available for digging. The rest will fall into Clint’s hands when breaking geodes – and this will be another challenge. Fortunately, bombs speed up mining, save you time, and can efficiently find a geode for you to collect.
Vault’s 25,000g Bundle
It’s an odd trade, but you’ll get a Crystalarium for paying 25,000g. Follow this separate guide if you need help in getting gold fast.
Find a Crystalarium Inside Treasure Rooms
Once you have the key for Skull Caverns, there’s a chance to find a Crystalarium in the Treasure Room. Drops depend on your luck, so make sure to bring lucky food items and rings! Assuming you have fixed the Bus, getting the Skull Key will be your final challenge – but we’ll help you with this guide.
If you don’t want to go through these missions, here’s your final resort: craft one. Once you have the Statue of Perfection, getting iridium ores and turning them into bars would be easier. But if you’re in your first year, consider relying on the alternatives above.
Setting Up a Crystalarium
Now that you have a Crystalarium, you need to place one of your gems, geode minerals, or foraged minerals inside. All you have to do now is wait as the machine does its work.
You might want to keep yourself busy, as replicating a gem or mineral will take hours or days. With that said, here’s a complete list of every item you can duplicate, their selling price, and the time it takes to finish the process:

Gifting and Profiting Tips
Profit-wise, Diamonds will be your best choice, and getting one won’t be hard either. At the end of the seventh day, you’ll generate 750g. It can even get higher with another 225g bonus with the Gemologist profession! Talk about a self-sustainable profit machine without needing a constant replacement.
On top of that, several villagers from Stardew Valley love valuable gems. Everybody loves Prismatic Shard, but here’s a simple table of everyone’s gem and mineral preferences:
|Amethyst||Abigail, Clint, Dwarf, Emily|
|Diamond||Evelyn, Gus, Jodi, Krobus, Marnie, Maru, Penny, Willy,|
|Emerald||Clint, Dwarf, Emily, Penny|
|Ruby||Clint, Dwarf, Emily|
|Topaz||Clint, Dwarf Emily|
Although Crystalariums can be a reliable side income in Stardew Valley, they won’t work with Prismatic Shards. The reason? It gives a negative EMF reaction to the machine. Set aside the science, you’re at a minor disadvantage because a single prismatic shard has different game-changing purposes.
