Leg. Gem Disappeared

I’m at a loss - s20 char, leveing gems w/ grifts. Up to around lvl 18 with gem of efficacious toxin. It’s not equipped anywhere, it’s in my stash. Log out and come back 15 minutes later. The gem is gone. It’s not in my stash, not on my followers, it’s not in the list to lvl from a grift and it’s not dropping a new one for me after completing a new grift. Help?

I didn’t search all three followers.

Tell your Enchantress that she needs to ask before taking your trinkets.

It’s on her.
