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, usually on cave walls, sometimes inside undercround cabins or the dungeon.
 * Protruding from a special background item resembling a rock.

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 Caves have their own unique background wall that cannot currently be collected or used by players.
