My idea for a use of adding rubies to the game

Ever sense I heard that rubies were going to be a thing I thought of what it would be like if we had them. I thought we would get to have the chance to experience that during the caves and cliffs update.

The purpose: The would have higher value than emeralds to villagers and you can buy more expensive items.

They could also be found in archeology sites and are used for jewelry for some sort of special ability like things are cheaper from villagers.
