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

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

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