Turquoise

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

Turquoises are fairly rare items found deep underground in the bottom 29 layers of the map but are not rare as gold in Usko, replacing Lapiz Lazuli and Redstone. They will be found in branches of 3-10. They require an Iron Pickaxe or better to collect. If you use Stone Pickaxe it must be Enchanted with anything.

Uses
Turquoises can be crafted to make Turquoise tools, which are between Amethyst and Diamond. Turquoise tools have 899 uses before breaking and will mine 1.5x faster than Diamond tools. They can also be traded to Villagers in Omberland.
