Those Good Ol' Unidentifiable Gemstones

So I made another bezel setting, this one a ring. It has a really cool purple and white stone, that I cannot for the life of me identify! The Etsy Forum Peeps did their best to help me out, but no sure answer was found. What do you think it is?? Use my poll at the right to vote. Update: 5/20/08 Poll Closed! Thank you for your votes! Sodalite came out as the popular vote though I have other hunches.
