To me they looked like water worn stones also, most were noticeably paramagnetic with the exception of some that were less...like the one you got from Steve. I saw this particular stone in Tucson (Steve showed me) and I think that he got from ET also. My impression was it was a water worn LL or L6. Especially after I saw the entire batch in a tray in Edwin's room. I myself went through these oddly shaped stones and found a few that had nice chondrules. I bought one that was also oddly shaped with folds, etc. and cut it, and sure enough it has chondrules...but it is more like a H4 (strongly paramagnetic). Could regular rocks be mixed in ET's group that included real meteorites like the one I got, possibly...or these were all found in an area that had conditions that created such oddly shaped meteorites. They are strange looking...but is yours(Steve's) an achondrite???...I don't think so, John Hi, app. 2 weeks ago, Steve Arnold (Illinois) sold a "mystery NWA" on ebay. This is the text that came with the auction (as often with Steve, no pic): "Up here for auction is a mystery.This is a 134.9 gram whole stone that has been cut by AL LANG.It is a unclassified NWA mystery stone.I had bob haag,richard norton,al lang,ed thompson,blaine reed, and a few others give thier opinion on what it might be.No one knows.It has a very rich dark brown matrix.Very few or none at all with chondrules.High in metal, but it pulls very weakly even with a strong magnet.You can be the lucky winner of this mystery stone and you can try and get it classified.It measures 6.5 cm x 5.2 cm x 3.8 cm.I will start the bidding at $1.00. Good luck." Well, I bidded and won the item. Today it arrived. I had a closer look at it, took some photographs and am looking for your expertise now. Let me describe the tactile impressions: The item is feels pretty cold when you hold it, and it has about the right weight for a meteorite of this size. However: the outside feels quite "soft", more like an ordinary stone than a meteorite, like a pebble that has been in the water. There is indeed a lot of metal visible from the outside, but on the cut surface, the deeper you go inside, the less metal you find. A close examination with a 10x magnification showed no chondrules at all, at least for me. Here are three photos of the object (they are quite large in order to reveal more details). I have brightened the photos and added some contrast and some mild sharpening, but I'd say they are true to the visual appearance of the object: http://metcollector.rendelius.com/mystery1.jpg http://metcollector.rendelius.com/mystery2.jpg http://metcollector.rendelius.com/mystery3.jpg So - what's your impression? Is it a meteorite at all? What is it?
