WotLK I lost an item Essence-Infused Moonstone

[Rado33335]

Hello, On my character named Lenivec (icecrown), i completed all the quest s required to obtain the Essence-Infused Moonstone.
I went to Sethekk Halls once, and the item has disappeared- i no longer have in my keyring.
Could you please restore it for me?
Thank you.

If it was your first time, I'm assuming it was for the final quest? Go turn the quest in, and you will get the permanent key.
