The Rapaport Group announced that effective October 1, the RapNet diamond trading network will no longer accept EGL International or EGL USA diamond grading certificates across its members-only platform, which is the world’s largest online diamond trading network.

In addition, RapNet will ban all green tinted diamonds no matter where they originated. Rapaport stated that 95 percent of green tinted diamonds are from the Marange area of Zimbabwe and there is too great of a risk of those stones being mixed with the 5 percent from politically stable mining areas.
