Alexandrite is Cool

  Hey everyone!  I'm in the middle of writing a research paper on Alexandrite which is a really amazing gem that changes color based on the light it is in due to chromium and witchcraft!  I probably wont post my whole paper when I'm done, but I am going to leave you with this picture and the site it's from and I highly suggest you look at how COOOOOOOLLL this is!!!!! <3
