Transparency In The Colored Gemstone Trade?

I found the article titled, Transparency In The Colored Gemstone Trade? interesting because the trade has been so different and secretive for so long, they abhor the thought of transparency and accountability. The colored stone market has no market control. The routes followed by colored stones to the marketplace are tortuous + far more individuals are involved, each with their own interests.
