I recently had a Sarin report done on a diamond--paid $35.00for the report. I had it done two places. And both came out to being very similar. But, to my suprise the sarin report differ fom the GIA report. The table on the GIA report read 67% and the table on the Sarin report (same diamond) read 72%. Should this happen? I thought both Sarin and GIA reports should be exactly the same. Please advice. All suggestion welcome--as I am confused. Thanks.
