This is the rubymod with rubys and rubytools. You can make rubytools (hoe currently not working as hoe), rubyblocks and mine rubyores (not tested). The crafting of the tools is just like the normal tools you can craft. I will say that this is my best mod so far, way better than the last one (EasyCrafting). I'm not sure what height you will find the ores on, but it's not higher than fifty. The ores have one in light effect and the stone around the rubys in the ores are a little lighter than normal stone and ores.

Note: this mod requier modloader

Installing the mod :
1. Download Rubymod for minecraft 1.3.2
2a. Open Rubymod v0.9
