If for any reason you would like to upgrade your GIA certified natural diamond to one of greater quality, Adiamor will apply the full credit of your original GIA certified natural diamond purchase towards the purchase of any new GIA certified natural diamond priced at least twice the original amount or higher. Your natural diamond must be in its original condition and accompanied by its original GIA diamond grading report. Please note that any diamond sent in for our upgrade policy will require inspection prior to finalizing agreement. Our Diamond Upgrade Policy applies to GIA certified natural diamonds only; on orders placed between January 1, 2012 and January 1, 2023.
