Emerald

An Emerald is an item dropped when emerald ore is mined or more commonly obtained through trading with villagers. It can also be found in desert and jungle temples.

Emerald can be used as a form of currency in exchanging items with villagers.

Uses
Emeralds can be exchanged for items and vice versa through trading, as well as powering the beacon block and building a pyramid-socket for it out of emerald blocks. To trade with villagers, right-click them, and a trade menu will appear. To trade emeralds with villagers, the player must place them into the trading menu's left slot in the amount requested above the slot. The player can then take the resulting item from the right slot. This applies conversely to obtaining emeralds in trade.

Bugs

 * Sometimes, when shift-clicking items from trading, emerald will glitch and will not be able to be used. The same goes for all items.
