Authentic Paraiba Tourmaline

I was a bit surprised with David Sherman's (CEO, Paraiba.com) move to sue the American Gem Trade Association (AGTA) and others—including the Gemological Institute of America (GIA), Brazil Imports Inc., and several individuals, including AGTA board members—for US$120 million in the name of authenticity, i.e., there is only one stone that can be legitimately called Paraíba and it is exclusively mined in the province of Brazil that it is named for + I was wondering what would happen to Padparadscha sapphires, John Saul rubies, Mogok rubies/ spinels, Mong Hsu rubies/spinel, Kashmir sapphires, Muzo/Chivor emeralds etc., + I don't know if it's a publicity stunt, but I am sure it will get messy in the coming days + as they say we are living in interesting times.
