The From Nothing Diamond in Path of Exile 2 drops as a possible reward from defeating The King in the Mists at the hardest version of the encounter, +4 Crux of Nothingness difficulty. It is also tradable, so players can buy it from the official trade system instead of farming the boss themselves.

How to get it

  • Reach the King in the Mists pinnacle boss encounter.
  • Run it at difficulty level 4 / +4 Crux of Nothingness.
  • Defeat the boss and hope for the drop, since it is not guaranteed.

Fastest practical route

  1. Unlock access to the Ritual pinnacle encounter.
  2. Save up the materials needed to enter the boss fight.
  3. Push the encounter to the highest difficulty you can handle.
  4. Farm the boss repeatedly until the jewel drops, or trade for one if you mainly want the item for your build.

What it does

The jewel is placed into a Jewel Socket and creates a radius around a keystone, applying its effect to nearby passives, so it is mainly used to enable build-specific setups.

Forum-style take

“Farm the boss if you can clear it consistently; otherwise just buy the jewel and move on.”

That’s basically the common advice here: the drop is endgame-locked and can be expensive enough that trading is often the more efficient option.
