amulet gone

hey i got these upgrade materials u can upgrade your amulet with if u right click them it opens a special menu where u can put the amulet and 3 of this materials.
so i put it there to just try it.
during the process i pressed escape and now my amulet + the materials are lost in the void aka the menu.
theres no hotkey to open it i think and im not having the materials anymore to right click and open the menu. somebody got the same problem or has an idea how to get my amulet back except farming for the mats again to open it and pray its still there?
