I did ALL of the Pandaria Remix Raids, but no necklace?

What am I doing wrong?

what difficulty - you need to do normal or higher

Has to be normal.

Normal. I am going to check if I missed a boss (I know I didnt, but I’ll look anyway)

they just put it in your bag and you might have to search for it - I had a hard time finding it as well.

Was it unlocked at the gem vendor?
