These are the known Archaeology items. The list does not include completed artifacts that you right click to create Restored Artifacts, as there are just too damn many of them. Instead, the addon scans the tool tip of your bags to find those. If that isn't working in your locale, please translate.
- All racial keystones as of patch 8.1.0
- Restored Artifacts
- All crates of fragments as of patch 8.1.0
- As many purchasable items as I could find on Wowhead
