[QUOTE="TIF, post: 3786623, member: 56859"]Some of the pallasites are notorious rusters (Seymchan and Brahin, for example). Some are noted for being more resistant (Esquel, for example). Prices reflect this. I've lost a couple of pallasites to rust. They were stored reasonably well but they fell apart anyway. All that was left was a bag of rust particles and chunks of olivine. Speaking of chunks of olivine from pallasites, there is a company who purposefully rusts the metal and saves the gemstone*. They facet the stones: peridot from space!! Super duper cool :).
