Lol I have the highest prices :P
Then again, I haven't really continued the shop in a while... I should get back in the business!

@TheBlizWiz Of currently somewhat active shops according to forum posts:
No shops currently have two-way exchanges. (IE if I have 64x I can get 1y out of the shopkeeper, where the price is 1y for 64x.)

Gold:
Haxington Oreburgh Mine: 8 ingots = 1 diamond
Andureil: ~14 ingots = 1 diamond
Ealdwine: 64 ingots = 1 diamond

Iron:
Haxington: 16 ingots = 1 diamond
Ealdwine: 64 iron = 1 diamond

Diamond:
Everyone: 1 diamond = 1 diamond
Everyone: 9 diamonds = 1 diamond block

Emeralds:
Ryebye: 1 Iron Horse Armor = 3 Emeralds
Ryebye: 1 Gold Horse Armor = 2 Emeralds
Andureil: Knockback 2 Book = 5 Emeralds

Cobblestone:
Haxington: 256 (4 stacks) = 1 diamond
Ryebye: 320 (5 stacks) = 1 diamond
Ealdwine: 384 (6 stacks) = 1 diamond

The first numbers listed are shops that have not recently been updated for a while. The last numbers are the shops that have been recently updated.

The value of different items are decided by its demand and supply of the market and individuals?

Why is that? Shouldn't they become less valuable as more of them are mined?

How though? Are people just burning the diamonds? Lol

Ah... Well I guess that is true...

Well I guess u can see diamonds as goods and a medium of exchange.

The thing is... Diamonds are too valuable to use as currency (At least for most people) This is due to the fact that so many things can be crafted from them. People as a result just stockpile them and become rich without ever spending them.

Heh this is just like a stock market report. Good stuff.

Just out of curiosity... How many diamonds does the richest player own right now?

What do you think is the average though?

Just diamonds or diamond blocks?

I only have about 25 diamond blocks but I'm sure someone has stacks of them or something
