Chiseled Polished Blackstone is a decorative variant of polished blackstone, commonly found in bastion remnants and ruined portals. It must be mined with a pickaxe, or it will drop nothing. It has a hardness of 1.5, making it relatively easy to break.
Chiseled Polished Blackstone can be crafted from two polished blackstone slabs or obtained via stonecutting from polished blackstone. It is primarily used for building and decoration.
