Taking Inventory: Emerald - Minecraft

Did I get paid in emeralds to write this article? Nope, in Minecoins : (

Someone once asked me what Minecraft’s villagers are doing with all those emeralds. Are they building a giant underground emerald fortress? Are they constructing a huge green monument to villager rights? The answer is much simpler.

They’re a currency! In the Minecraft world, emeralds are a medium of exchange for goods and services – just like coins and banknotes are in ours. Players, villagers and wandering traders use emeralds to represent the value of those goods and services, because it’s easier to carry around one emerald than, for example, 15 bits of coal or 26 potatoes, as any of you who’ve tried to exchange 50 potatoes for a copy of Minecraft at your local games emporium will know.

Emeralds were originally added to Minecraft in January 2010, but then they were renamed ‘diamonds’ and everyone forgot about them. In 2012, Jeb implemented a trading system, and initially it used rubies. It wasn’t until a few weeks later they were replaced by the emeralds that we recognise today. I guess we were saving rubies for another game.

There are four ways to get hold of emeralds. The first is by digging them up out of the ground. Emerald ore is found only in extreme hills biomes, and it’s pretty rare so good luck with that. The second is by finding them in chests – emeralds are a common reward in ruins, igloos, villages, shipwrecks, jungle and desert temples, End cities, and more. 

The third is that vindicators and evokers will sometimes drop emeralds on death. But the final, and probably easiest, way to acquire loads of emeralds is by trading with villagers and wandering traders. Go chat to a villager and they’ll tell you what they’re willing to exchange. Trade a lot, and they might offer more options.

I covered real-world emeralds when I wrote about them in my much-missed Block of the Week column, so rather than repeating that, let’s talk about currency.

Money in the real world started out in the form of receipts – representing grain stored in Ancient Egypt and Mesopotamia. Metals were used as symbolic of the value of the grain, because they were hard to obtain but easy to carry. But defending those grain stores was difficult, and the value of the currency was only as strong as the power of the military protecting it.

Coinage emerged next – carefully weighed out and stamped by the authorities as certification that it contained the right amount of a precious metal – gold for large amounts, silver for smaller, and copper for the smallest. These standardised weights formed the basis of the system of banking. 

Paper money emerged first in China. They were originally receipts for deposits of coinage, exchanged by wholesalers’ shops, and valid only in the local area. But in the 10th century, the Song dynasty expanded their use and created the first state-issued currency. At around the same time, the medieval Islamic world invented many modern economic tools – credit, cheques, savings accounts, loans, trusts, exchange rates and more.

Today, the global economic system is enormous and has a huge influence on our daily lives – some would argue too much. Currencies are largely issued by governments of sovereign states, but airline loyalty points and credits in MMO games can also be considered valid currencies and are regulated as such.

In recent years a collection of decentralised “cryptocurrencies” like Bitcoin has emerged. It’s too early to tell if these are the future of money, or just a fad among technologists. If they do take over, then perhaps we’ll need to rethink how trading works in Minecraft. For now though, it’s emeralds you should be mining!
