Lost abysal jewel from disconnect (Frankfurt server)

Hi,
I was just about to transfer i believe an abyssal jewel (the ones that can be used in belts), had the jewel in "hand" wanted to move it from inventory to the stash when I got disconnected.
Upon relogging the jewel is gone.

Is there anything that can be done to get that jewel back?

GGG does not offer a service for items being lost through disconnects or game crashes.
