 * 1) Ruby ore was originally added into minecraft java edition and was a "before" emerald ore, the ruby block had the same texture pattern as the emerald block today, in fact, the ruby ore also looks like the emerald ore today, and ruby's were originally the first emerald ingot's or ore. But when notch got rid of the idea, the idea of emerald's were implemented into the game. And in the java edition of minecraft, you could instead trade with villagers by using ruby's, but in today's minecraft, you can only use emeralds.
