Prior to working closely with NFTC, we have did a look up ourselves regarding the address and the telephone number that was given to us. On top of that we also checked
GB/T 16552 and GB/T 16553 is also the standard numerical code that is familiar in the gemmological industry, representing the standard code for gem testing. GB/T 16552 stands for Gems - Nomenclature (unidentified gems and also jade), while GB/T 16553 would meant Gems - Testing (where tests are conducted). The former would meant the handling of such materials before it was identified and the latter would be the test conducted to identify them. I'll include the links before for references.
