Emerald ore is an extremely rare mineral block that only generates in Extreme Hills or Extreme Hills Edge biomes and drops emeralds when mined with a diamond or iron pickaxe. It drops 1 Emerald from each ore block mined (1-4 if Fortune III is used) and does not require smelting (much like coal, diamond, redstone and lapis lazuli). It drops experience orbs when mined, worth 5-7 experience, unless mined by an iron or diamond pickaxe with the silk touch enchantment. Instead of generating in veins like other ores, it is encountered as a single block, and tends to be very scattered around. It is also the only ore with a texture that looks to be small square gems embedded inside the ore, unlike the small, broken rectangles seen on the other ores.
