Gems
Gems are valuable crafting materials found underground. There are currently 7 Gem types. Gems can also be placed on any side of a block after being mined. They are found in any Underground layer, except for the Underworld.
With the exception of Amber (which requires an Extractinator instead), Gems are found in the following forms, all of which drop Gem items when mined:
- Embedded within Stone blocks.
- In placed form on blocks underground, including sometimes in Underground Cabins, or rarely in the Dungeon.
- As gem stashes, which are breakable background objects (similar to Coin Stashes), each resembling a rock with gems protruding.
Gems can also be found in higher concentrations in rare Gemstone Caves, which can contain multiple Gem types lining and embedded within their stone blocks.

Gemstone cave[edit | edit source]
A Gemstone cave is a rare, irregularly shaped room often found in the Cavern layer. They contain a high concentration of placed gems on multiple stone surfaces, as well as a few gems embedded in stone. Most gemstone caves contain one or two types of gemstone, but can rarely contain three or more types. The type of gem found in such caves is easily identifiable by the Gem Wall the cave utilizes, but this wall cannot be collected to obtain any items.
Notes[edit | edit source]
- Caves with Dirt background walls are considered to be within the Surface layer and will not contain Gems.
- Gem rarity is not affected by depth; you will find just as many Gems just below the Surface as you would near the Underworld.
- Gems are less common in the Underground Jungle. Regular non-Jungle underground biomes contain much greater quantities.
- Making Stained Glass is the most profitable way to sell gems. (Except on
Mobile where it's less valuable.)
