Emerald is an extremely rare gem in Minecraft (even rarer than the Diamond). It is the main currency used in the Villager trading system. Emeralds can be mined from Emerald Ore, which can only be found in Extreme Hills Biomes and Roofed Forest Biomes, making them extremely rare to find. Emeralds will only drop when mined with a Pickaxe made of Iron or Diamond.
