Hi Adam. Yes, we completely understand your confusion
over all of the different TKW's reported. That is why
we are attempting to clarify this issue once and for
all. The important thing to note is that the TKW now
stands at over 10kg. NAU's website will eventually
need to be corrected as will the provisional Met
Bulletin once we get this TKW issue sorted out. The
TKW of NWA 2714 is 1666g, not 100g. According to the
classifying Scientist, our NWA 2714 came from the
7.5kg whole stone that now appears to be wholly
accounted for by Stan's and Nelson's portions.
Therefore, since that obviously is incorrect, our 1666
grams of NWA 2714 either came from a larger stone that
was broken into fragments which were then sold to
Stan, Nelson, us, some others and perhaps you, or
perhaps it was a separate individual (I doubt the
latter). We try to keep our website updated to reflect
the new TKW as we understood it 40 minutes ago. Of
course we will now need to further update it once we
tabulate the additional masses of other pairings
kindly provided to us by list members. We'll be happy
to share this total with you once we get it so that
you can update your ebay auctions too, but for now I
think it is safe to say there is more than 10kg of
this beautiful material in existance. It is important
to properly report the TKW so that the collectors know
the facts as we currently understand them.


Cheers


-John
