The Block of Ruby is a block added by the GEMS! idea pack. It is the mineral block equivalent of Ruby and counterpart of the Block of Sapphire. This makes it rather rare, as Ruby Ore is difficult to find. Like all mineral blocks, it is crafted with 9 Rubies in a square. It can also be crafted back into 9 Rubies.
- Put 9 Rubies in a square
- Makes 9 Rubies
