Jeweler problem with Orb quality gems.
The reason the tooltip only list them for artificer is because there are no Tier 6 (400) discoverable jeweler recipes for the Orbs. You must filigree them using a Karma recipe (available at the master jeweler) before you can make the accessories.
Ah, thanks. Now that I know what to look for, it is on the wiki, but it’s not obvious. Maybe a note would help if others run into the same problem.
