Rare Ores are Ores which have a very low chance of spawning. In the Material Index, their rarities are displayed as '???' until discovered for the first time by the player. Most rare ores are not tradeable, and must be mined to be obtained. Most rare ores also have unique particle effects and emit sounds.
