Dear fellow enthusiasts,


Here in our actual Special, we want to introduce a carbonaceous beauty, a
new CO3:? NWA 6021.


CO3s were and are still a little bit underestimated in the favorableness of
the collectors.
They never got the popularity of the CVs and CMs, most probably, because
they hadn?t these massive falls like Allende and Murchison
of the direct Apollo-period, which consequently were not only easily
available, but discussed at length and pictured in each and every popular
book. While the most important CO3-fall, Kainsaz, was locked away for the
collector behind the iron curtain, else there were only Lanc?, Ornans, Isna
and Colony ? all with very modest tkws, museum stuff, with limited
opportunities to gather a small cut ? and so costly, that the whole class
was something only for the very experienced and specialized connoisseur.
Really available the CO3s became not before the 2nd half of the 1990ies,
when the finds of the larger pairing group of the DaGs in Libya were made.
Additionally another reason might have been, that CO3s are of not so
striking first appeal, but CO3s require a closer look.
Though that attitude has already changed a bit with the fall of Moss.

And do you know what?
The novercal neglecting of the CO3s by the collectors is absolutely
undeserved.
One has to examine these rocks only a little bit en detail, if you allow
them to come only a little bit closer to your eyes,
an incredible cosmos will open to you, richer than in any other of the
carbonaceous types!

CO-chondrites have chondrules to excess, sharply defined and not very
metamorphosed.
Their matrix is similar to that of the CV3s, as well as the chondrules
composition, they?re only much more smaller, so small like those in the
CM2s,
but they have three times more chondrules than the CMs ? and they have many
more olivine aggregates than the CV3s.
And yes, they contain CAIs too, the reason, why you bought once your first
Allende.

One has it all and more than that ? but on a miniature stage.
Take a magnifying glass and you?ll recover what for a wonderful and
fascinating affair the COs really are.


Now with NWA ?6021 we?re glad to introduce an aesthetically especially
pleasing representative of that class:

Densest clouds of chondrules!
To some of you immediately will come the gimmicky title into mind once
attributed to the later Kainsaz-finds:? the ?Space-van-Goghs?.
But other than with these, the stainings causing these wonderful patterns
are in NWA 6021 not so brown oxidized.

For you being able to enjoy the full beauty of this meteorite also on a
minor scale,
the slices are of course professionally polished.

The price for these daedal pieces of art by nature,
is somewhat under average, the slices are of good sizes and though for every
purse affordable.

And we are convinced, that your specimen will bring you satisfaction and
hours of joy on long winter?s evenings.

All the best,
Stefan & Martin
