Hi Mike,

no worries, neither we understood it like that.

Of course, if one looks to the photos, the first idea, which comes to one's
mind is: oil.
No idea, what causes this effect, maybe the composition. Also that strange
tint the cut faces reveal.

And especially worrying is the variety of the odd inclusions. I mean
normally we all get already excited, whenever we find a carbonaceous
fragment in a howardite,
but what that stone has all for strange clasts - that is really not normal
anymore.

Since 1999 Stefan is in Morocco and since then we certainly had quite a
bunch of materials in our hands,
but such a weird polymict one - extremely unusual.

And it seems that many collectors feel the same, if after such a short time
now only three slices are left.

Now all of the smaller ones are gone, sorry for that. But we have still a
slice left, which we could subdivide into small partslices, if desired - but
for that one has really to raise his finger.

For the moment!
Martin

Howardite - NWA 6709 - absolutely stunning and very fresh.

Hi Martin,

I didn't mean to impeach the meteorite, I was just curious.

This is indeed a mystery. Have any scientists offered or agreed to
look at it? Perhaps hit the rainbow area with the microprobe or SEM?

Aesthetically speaking, it's gorgeous and looks like Mother of Pearl. :)

Best regards,

MikeG
