Block 03: Diamond Ore

  In the deepest depths of the earth....  Surrounded by lava pools is a stone studded with light blue gems.  It's diamond ore!  Diamond ore is the third block in the creative inventory.
  Diamond ore when mined with a iron or diamond pick yields one diamond.  You can only find diamond ore in the lowest 16 layers of the earth.  You can only obtain diamond ore with a silk touch pickax.  Diamond ore is found the most between layers 12 and 5 as shown in the picture.  Diamond spawns in veins of 1-10. Diamond ore can be smelted to make diamonds.
  Overall diamond ore is a very useful block in minecraft.  It's the rarest of all blocks.  So when you see diamond ore go for it!
