These are definitely Black Sapphire:

See the last few 320iSE Pictures at the bottom of the page, shown with the front carbon fiber lips in the showroom. It almost looks a little like Monaco Blue, but its not, that's just the metallic black difference.
I went to the dealership last week and didn't have my camera, but they had both Jet Black and Black Sapphire. Both look great.
