Steve, not saying anything bad, simply letting you know what the lab told me, hopefully before many other people decide to cut pieces.
This meteorite when broken, retains all minerals, crystals (and there are
Many) volatiles etc, even when down to the smallest pieces.
Again, you can do anything you want, I am not stopping you. Just letting you know that this is one of the rarest
Meteorites we have ever seen, that's why Greg and I decided to donate some grams to the UOfA. I really hope most is preserved in the best forms possible for future science.

The slices I have now, while they are not useful anymore for SOME research and some examination purposes, they are however are VERY interesting (at least to me) in what they show. I see things that quite frankly, I am not sure one can see from a broken fragment.
