Not to forget to mention, that not in each and every specimen of a find or
fall, the Neumann lines are likewise developed.

Sometimes they will appear extremely sharp, sometimes faint, some pieces
won't have any - and that is independent from the preparation mode.

What a striking point, Sergey! My Guadalupe y Calvo just looks the same in a
plain simple photograph. :-) We learn it?s all a matter or light and
photographic skills and everything else to get "the real thing" transported
to another viewer, and even when showing such a specimen to another person
right on a spot, you have "to turn it here-there, left-right", just the way
you well described it!

Thanks for this alternative picture, very good indeed in comparison!
