Hello List and Diogenite buffs,

Last month, there was an advert from Chladni's Heirs (Stefan + Martin)
and Martin offered what he called a "crazy diogenite". TKW is a mere
69 grams. I don't know if there are still any slices left but 2 of the 3
pieces I am glad I was able to purchase have a special feature, something
I have never seen before in any of my diogenites - at least not with such
clearness (only exception: my back-lighted Tatahouine RFS picture of
October 3, 2007: http://www.spacerocksinc.com/October_3_2007.html)

My two NWA 4808 diogenite slices feature textbook examples of several
large euhedral (= mineral crystals fully bounded by well-formed typical
crystal faces and subhedral (= having a partial or incomplete crystal face
or form) orthopyroxene crystals in which the cleavages (= most minerals
break or "cleave" along certain planes and pyroxenes have two cleavages
at 90?) are clearly and unmistakably visible.

So glad I didn't hesitate and acquired three of these exotic beauties!

Diogenitically
Yours,

Bernd
