Ruby is a gem added by various mods, including RedPower 2, GregTech and Biomes O' Plenty. It can be obtained by mining Ruby Ore, by combining Ruby Fragments, or with UU-Matter.
Note that only the Biomes O' Plenty version of the ruby can be used to create the Ancient Staff Topper. Any other type of ruby from any other mod will not work.
Alternatively four Ruby Dust and 24 Industrial TNT may be processed in an Implosion Compressor to create 3 Rubies and 12 Dark Ashes. The process takes 1 second and requires 640 EU.
