All functionality was replaced by emeralds.
Rubies were originally planned to be added as part of Minecraft Java Edition 1.3 as a currency for trading with villagers, but were abandoned at the last minute in favor of emeralds due to developer "Dinnerbone" being red-green colorblind and therefore having a hard time spotting the difference between Redstone Ore and Ruby Ore.

- There are many mods that can be used to put rubies back into the game, however, they aren't always identical to how the original ruby concept worked.
