Rubies are used to trade for in game stuff, you can look for wizard npc in spawn, he trades rubied for kill messeges, claim blocks and other in game stuff.
And all crates have been removed except vote crate, but i think voting gives you rare crate key in survival so there no point as rare crate doesn't exist, still you can try and open vote crate by /crates command.
