Emeralds are a rare mineral obtained by mining Emerald ore or looting chests in structures such as villages, shipwrecks, buried treasure, and bastion remnants. They are primarily used as the main currency for trading with villagers and wandering traders.

Emeralds can be acquired by trading various items with villagers, making them one of the most renewable and valuable resources for obtaining enchanted books, tools, armor, and other rare items. They can also be crafted into Emerald blocks for storage or decorative purposes.

Since emeralds are mainly used in villager trading, they are essential for players looking to access high-level enchantments, rare resources, and efficient item exchanges.
