Pearlstone Block

Pearlstone is a Hardmode block type found in The Hallow. It requires at least a Nightmare Pickaxe, Deathbringer Pickaxe, or explosives to mine.

Pearlstone is the Hallow version of Stone (similar to Ebonstone in The Corruption, or Crimstone in The Crimson). In a way similar to Ebonstone and Crimstone, Pearlstone can be converted into ordinary Stone via Vile Powder, Vicious Powder, or the Clentaminator with the Green Solution.

During the initial creation of the Hallow biome upon the defeat of the Wall of Flesh, Stone blocks in the conversion path become Pearlstone blocks (see Hardmode). Pearlstone itself also continues to spread Hallow to all Stone, Sand, Ice, and Grass covered dirt within a three tile radius. Over time, it will grow Crystal Shards if it is in the Underground or below.
