The Ruby Pack

This resource pack turns diamonds into ruby. it changes: names, diamond, diamond tools, diamond weapons except the spear, diamond block, diamond horse armor, diamond armor, enchanting table corners, armor trims, smithing templates and upgrade templates. 

There are 2 versions: a version where ruby ores have diamond colored outlines so you can see a bigger differense between redstone and ruby, and a version where it doesn't. to choose the version go to files and install the one you want.

this project is available on curseforge and modrinth.
