The Ruby is the first ore that was added to this mod.

You can create tools and armor from it

Aluminium is almost like iron but a tiny bit better. You can create tools and armor from it

Lavite is found inside the nether. It's one of best ores that have been added so far. You can create tools and armor from it

Voidite can be found in the Bedrock Dimension and only with this can you escape that dimension. Voidite can not be used to craft tools and armor at the moment but in the next version you will be able to do that
