Just another ruby is a mod that adds rubies and gems as new mineral resources that we can find underground. These gems and rubies will allow us to develop a large amount of content, mainly equipment for our character, such as weapons, pieces of armor and tools, which in some cases will be more powerful than diamond ones.

Beyond the items we can craft from the rubies and gems that this mod adds, we can also craft tools, weapons, and pieces of armor from lapis lazuli and emerald. We can also make a prismarine helmet that will give us night vision and underwater breathing, or shulker armor, which will eliminate fall damage.
