This is my first mod it just adds a Ruby Ore and Ruby and Emerald Armor and Tools. It also adds a new Apple that is just the same as the Notch Apple (Enchanted Apple) and a Ruby and Emerald Block that emits light.
Ruby Ore is very rare and spawns in the overworld at the Y levels 1-13. It can drop a maximum of 4 Rubys per ore.
Probably will never update
