gia being wrong

i recently bought a stone that was represented as a vs1, I color brilliant cut stone with faint flouresence (1.79 carats if that matters?) when i got the ring appraised by a very distinguished and reputible appraiser (to remain nameless, but he has every designation one could want, etc...) the ring appraised as a G color, no flouresence, and vvs1. now i can understand the clarity rating, but the color and flouresence confuse me...can the gia be that off? the ring was compared to master stones and put into a machine for both color and flouresence. if the ring did have faint flouresence i could understand it grading as an I, but looking like a G...just a little confused? i had a long talk with the appraiser and asked him not to "jack up" the appraisal rating, etc. but he swore that that is what the stone really was.

i paid a great price for an I, vs1 stone, but a ridiculous price for a g,vvs1 -so i am pleasantly suprised. it does not mattter all that much, just wondering why maybe the discrepency.

Has your appraiser checked the mounted or loose diamond?

Truthfully, the GIA does reconsider the grading of diamonds on a regular basis and does sometimes change the grade. Rarely would any dealer request a revision to a lower grade, so the certs in circulation always represent correct or slightly high grading. If a dealer gets a "too low" grade from GIA, the cert is tossed aside in favor of some other lab's more liberal report. This is a rather common practice if the grading cannot be resolved with the GIA graders.
