Emerald Ore

Emerald Ore was added in the 0.9.0 Update. It is the seventh ore to be added to the game after Coal Ore, Iron Ore, Gold Ore, Redstone Ore, Lapis Lazuli, and Diamond Ore. Emerald is also the one of the rarest of all ores, typically found in veins of one, but sometimes as high as two or three.

Obtaining
Emerald Ore mined by using a Iron Pickaxe or stronger, and when mined drops a single Emerald. They are only available within the Extreme Hills Biome.
