Ruby is a biome-specific Gemstone introduced with Biomes O'Plenty. It appears as an ore, an item, and a decorative block.
Ruby Ore can be discovered in desert biomes. A current list of these biomes can be found under Ruby Biomes.
An Iron Pickaxe or better is required to mine Ruby Ore. A Silk Touch Pickaxe can be used to collect the block of ore rather than the Ruby drop. The ore drops one gem with an unenchanted pickaxe. With fortune, the ore can drop up to four gems, one extra per level of fortune. Ruby Ore cannot be smelted.
9 Ruby can be crafted into a Block of Ruby for storage or decoration. These stack to 64.
