Gems

Gems are a valuable material that can only be found in veins underground, embedded in Stone blocks, which will drop the gem when mined. Unlike ores, gems cannot be placed again after being mined.

Each gem type can be used to create a Phaseblade of the matching color, though each color Phaseblade has identical attributes. Topaz can also be used to craft the Sandgun, and Rubies for the Gold Crown and the Robe. Additionally, each component of the Jungle armor requires 2 different gems to be crafted; crafting a full set requires gems of all types.

Gem rarity is not affected by depth; you will find as many gems near the surface as right above the Underworld. However, gems are far more common in the Underground Jungle. Some gems are less common than others; refer to the list below for each gem's rarity, in descending order.
