Several times I've heard VB say "pink and Green are the rarest colours of Tourmaline". Correct me if I'm wrong (and I could be as I'm not always perfect, just most of the time ) but I would have thought that Paraiba, Rubellite, Watermelon, Chrome Tourmaline and Indicolite as well as all the Bi-Colour Tourmalines, are all rarer than the Pink and Green?
