A few years later the boundaries of the upper color zones in relation to the "old terms" were altered once again to a minor extent in order to tally with the GIA, Scan.D.N. and CIBJO. The upper; half of the F zone is no longer classified with the color-grade River, but is unequivocally put down into the color grade Top Wesselton.
