With titan-like inscriptions like that on its facets, nothing less than Ironforge's Hall of Explorers is the right place to bring it.
I'd like to think that you'll be noted in the history for it in the catalogue -- "Recovered by <name>! Authenticated by Prospector Whelgar..." Ah, I'm gettin' meself carried away.
High Explorer Magellas will receive you, and given the exquisite nature of what you carry, will surely be most generously appreciative should you donate it to the museum.
