Sapphire

Note that this does not exist in Minecraft; it was written purely as a fiction article.

Sapphires are fairly rare items found deep underground in the bottom 35 layers of the map. They will be found in branches of 5-10. They require an Iron Pickaxe or better to collect.

Uses
Sapphires can be crafted to make Sapphire tools, which are in-between Iron and Diamonds. Ruby tools have 754 uses before breaking and will mine 1.5x faster than Iron tools. They can also be traded to Villagers or Khutonese.
