I love the look of ivory, and I understand they hold up and age well, too. I don't like that idea that animals are harmed to get it and I don't super trust the typical sources to be on the up and up.
However.... Mammoth is extinct, so I have no problem with that since I didn't kill anything to make it happen. I really love the look of Mammoth Tooth, but I have been shopping (half assed) for a nice set of off white for a 1911 for the last 5+ years. with young kids that $400 can be better spent elsewhere, and something more important always shows up.
