I like the slice of "Blue" with an attached rhyolite pebble. http://www.lunarrock.com/nwa2828/nwa2828pebble.jpg It is one thing to look at this material now with the knowledge of what it is. I can only call it astonishment when you cut into one like is shown in Greg's image. But Greg, what was it like to cut into a blue meteorite when it was new! I'm sure you had ideas of what it was but this was before any classification/analysis had been done. What did you think when the first blue meteorite was cut?

Before the realization that NWA 2828, Al Haggounia and the other pairings to NWA 2828 were found to be an EL3 and NOT an aubrite, I spent many trips to Morocco buying up the "Blue" material. Needless to say, I have several kilos of the "Blue" EL3 material, one of the lucky first-in buyers, not price-wise but material-wise :-) Here are some additional photo links of NWA 2828 "Blue", most have seen these as they are the ones I have with my eBay description of NWA 2828.
