"No two diamonds are alike and neither are their grading certificates."
A survey by RapNet -The Rapaport Diamonds Trading Network found significant differences between laboratories grading the same diamond” says Avi Kravitz (Rapaport News). They ranked the laboratories in order of accuracy and consistency and GIA – The Gemological Institute of America ranked number one.
Jewelry Insurance News, in their newsletter (May 2011), recommended that their agents and underwriters rely on reports from reputable labs which they listed as GIA, AGS and GCAL.
