With ORAS almost here why not have a nicknaming thread to share, rate, and think up nicknames for the Pokemon we'll be using?

I'm going for a naming scheme named after locations (i.e. Galapagos the Sceptile, Vesuvius the Torkoal, Hokkaido the Bisharp, etc), but I'm trying to come up with a good name for Sableye here.

Something relating to his gem nature and such, has to be a location. Any ideas?
