I can’t find one of my legendary gems in my inventory. It is still available for upgrades after finishing a rift. I only have one character and have never used followers. I am playing on the Nintendo switch, so the inventory page suggestion for pc players is of no help.
Any suggestions for figuring out where the gem could be? Any level requirements that would keep me from seeing it?
…but, even if the inventory pages section isn’t relevant on console, the underlying principle is, i.e. if Urshi offers to upgrade it, it’s in one of these locations…
Your hero’s inventory
Socketed in your hero’s gear (i.e. rings / amulet)
Socketed in your follower’s gear (i.e. rings / amulet)
In your Stash (either in its own slot, or in a ring / amulet)
Does the console version of the Stash have a filter box like PC where you can type the name of an item to highlight it in there?
You could try going to the gem artisan’s remove tab. It might show you it is socketed in an item and which type of item to help you checking stash/inventory/each of your followers.
