How to Obtain

You can find the Faceted Rock Gem in the Deep Earth section of the Mines. The primary method is digging at Archaeology Dig Spots using any Pickaxe or Shovel.

Players have also reported finding it on floors 41–60 of the mines, which corresponds to the Deep Earth biome. This is consistent with the artifact's Deep Earth Set classification.

Stoneturner Skill

If you have the Stoneturner Skill enabled, you can also find Faceted Rock Gems when breaking rocks in the Deep Earth. This gives you a second way to obtain the artifact while mining.

Tips for Finding It Faster

  • Focus on digging every Dig Spot you encounter in the Deep Earth floors.
  • Enable the Stoneturner Skill to gain additional chances from breaking rocks.
  • Repeat the process — the artifact is uncommon, so multiple trips may be needed.
