I have found a rather large diamond inside the newly classified NWA 6871 ureilite meteorite (provsional) While it may be small for a diamond, I have not seen any "holdable" diamonds from meteorites or read about them, as this one is. Its only about the size of the ball in a ball point pen and weighs roughly .025g but is a stunning sight and was found in a slice of a very shocked and unusual ureilite. I though some of you may like to see it. I am calling it the "Gump Diamond" as it is the shinning example that "meteorites are like a box of chocolates, you never know what your gonna get" Close up of diamond http://i27.photobucket.com/albums/c165/jedisdiamond/DSCF5281.jpg Diamond with scale cube http://i27.photobucket.com/albums/c165/jedisdiamond/DSCF5332-1.jpg More to come on this awesome find soon.

Personally, I share the same sentiment as most of you - it would be heresy to destroy a meteorite to extract something that is available here on Earth, even if it wasn't cost-prohibitive. At 41 years old, I have made it this far in life with terrible math skills, so this old dog isn't going to take any refresher courses.? I was hoping one of the more skilled (and intelligent) members would act as a human calculator and cipher this question for me.? :) So in this particular case, the 32kg iron meteorite contains ~1.5 troy ounces of gold, with a current market value of ~$2550. What sparked my curiosity was the apparently high gold content that was measured in milligrams and not the usual micrograms one expects to see. One last question, perhaps rhetorical in a sense, has anyone ever seen gold in a meteorite?? I mean, has there ever been a visible "bleb" or gold inclusion in a meteorite?? Or is all of the gold bound up on a molecular level and invisible to the naked eye and 10x loupe? I guess there won't be a gold rush to the asteroid belt....
