Stardew Valley Crystalarium   Crystalarium


The Crystalarium is a craftable item used to duplicate Minerals and Gems, with the exception of Prismatic Shards. Insert the mineral or gem you wish to duplicate, and the process will begin. Each mineral or gem takes a different amount of time to duplicate, see duplication chart below. Note that once you insert an item, you can no longer remove it.

Apart from crafting, a Crystalarium can also be obtained as a reward from donating 50 items to the Museum, or by completing the 25,000 Bundle in the Vault.
