Minecraft (Pocket Edition)
Emeralds are mined from Emerald Ore, which is found deep underground often near the lava layer.
Usage / Purpose
Emeralds are currently a decorative item. They can be crafted to form a Block of Emerald, which is used as a building material.
Drops / Yields
Each block of Emerald Ore drops on Emerald.
Emerald is stored in stacks of up to 64 units.
Despite the relative scarcity of Emerald, it currently lacks any use other than as a decorative block.
