Ha! I knew when I posted that picture that someone would notice that. Should've figured it would be you.
It is, in fact, Pelikan Edelstein Emerald. At work my choices are black, black, or black, but this evening I was taking notes for a class I just started, so I inked up a pen with something interesting.
Emerald? Did you mean Aventurine? Either way, it looks like a nice green.
