A 2.5mm silvery metallic grain with a halo of probably Pyrargyrite, an identification key. I wouldn't be able to post this specimen for it not from my source, which was Dr. Jaroslov Hrysl, author and expert on rare minerals. There may be much more than just at the arrow, although with other sulfides present it is hard to say.
