With the help of John Kashuba from California who also bought a piece of this meteorite, it appears that my nice Diogenite is more like a LL4 or maybe even LL5. That would explain the metal, and lack of apparent chondrules on the weathered surface. But the crust so, so nice. :)

I'm so good at this... :( I need to stick to what I know or don't know, and not guess anymore.

Thanx to John K who exposed a surface for visual analysis. One of John's pics is below. A very nice amphoterite.

> Hello all,

> This morning I finally got to look at a new fragment of a meteorite that Dean
> Bessey sold as an un-cut, unclassified meteorite that is probably an LL. He sold

> The fragment has a nice black "melted" crust, not unlike many HED meteorites.
> There is a pull with a strong magnet similar to an LL. Not weak, but not strong
> like an L. There are no signs of chondrules on the slightly brown-weathered
> broken faces. Looks like a fair amount of orthopyroxene sticking through.

> To me it is a nice Diogenite, but I have yet to cut it. I was wondering if
