Atlas Stone (or Atlas Shards) occur when harvesting metal from lodes. The Atlas Stone can not be gathered by the gauntlet tool, but you have to pick it up with "E". The Atlas Stone drops off the lode if the lode is destroyed by harvesting it and therefore can drop into the void.

Atlas Stones are needed for crafting Atlas Core and the Atlas Core Upgrades. Also you can craft an Atlas Lifter for making things levitate to pull them somewhere.
