my question is... if it is ok to add the pvp after i make the CG ( when it is already red ) and stirr it hard enough so the pva dissolves in the water and capp the gold nanoparticles?

I've done exactly that. I used this PVA http://www.sigmaaldrich.com/catalog/ProductDetail.do?lang=en&N4=363162|ALDRICH&N5=SEARCH_CONCAT_PNO|BRAND_KEY&F=SPEC. Simply add the PVA to hot (not boiling) CG with vigorous stirring. I did this not for stabilization, but to make films and pucks. See the attached image.
