In this mod I added a ruby ​​ore to the game and added items, armors and tools made with it to the game. 
Since it's my first mod, it may contain some bugs.
You can find the crafting of items and blocks when you download the mod. Do not forget to point out the errors you find in the comments. Thank you for your understanding!
