Hi Martin, Steve, all...

Let's call them "chocolate & coffee fusion crusted meteorites"!
Cheers

Hi Steve, Fred, all...

Marvelous!

Now we saw examples of Bensour, "Mauretania", Chelyabinsk and have from old
literature Pultusk and Mocs..

...seems that Captain Blood's "Orientata" needs a new chapter:
"Color-Orientation"!

(Fascinating, after such a long time spent with meteorites, we from the
Meteorite House weren't aware of that phenomenon,
you always can learn something new!).

Though we have to have some discipline and to be cautious, not to establish
a new artificial hype or to create a new fashion, multiplying the prices,
as it had happened, if you remember, first with the "hammers", then with the
"meteorites with holes" and again afterwards with the "irons with impact
craters".

At least now the Ensisheim visitor have an additional hint, what to look
for, if they'll rummage the tables of the Russian colleagues, which will sag
from the loads of fantastic Chelyabinsk individuals.

Cheers!
Meteorite House
