Material Assistance

<name>, there is a pressing matter I hope you can help with... both materially and spiritually. Allow me to explain. Within the depths of the Scholomance in Lordaeron is a chamber called the Great Ossuary. I need to complete a device that would pierce the shadows of this horrid room. To finish what I have started, I need two diamonds: an Azerothian and a Pristine Black. These are not trivial items, I know - I just don't have the resources myself. Could you provide me with one of each?
