Over the last two weeks, two diamond trading networks have banned grading reports from the European Gemological Laboratories (EGL). The RapNet Diamond Trading Network will no longer list grading reports from any EGL branch effective October 1st. And as of September 17th, the Polygon diamond trading network delisted all EGL International grading reports and restricted the sale of diamonds with those reports on its buy/sell channels.
Why have the EGL reports been banned from these major trading networks?
