Premier Diamond Group on Four Main Grading Labs of the Industry

(Entertainment-NewsWire.com, March 12, 2022 ) Ontario, Canada -- If one is in the market to purchase or sell a natural colored diamond, it is advisable to have the gem evaluated by an independent grading laboratory. The purpose of this evaluation is to ascertain the quality and price of the diamond. After evaluation, the diamond is given a report that can “help differentiate stones based on important characteristics that determine quality and aesthetic,” according to Helzberg Diamonds.

The following are top four diamond grading institutions: Gemological Institute of America (GIA), American Gem Society (AGS), HRD Labs, and Gem Certification and Assurance Lab (GCAL).


This is a well-known grading lab that was established in 1931. It is “the world’s foremost authority on diamonds, colored stones, and pearls,” according to its website. This nonprofit institute is the leading source of knowledge, standards, and education in gems and jewelry. The industry considers GIA as the standard bearer in the diamond industry.


Like GIA, the American Gem Society (AGS) is a nonprofit. AGS Laboratories is dedicated to offering diamond grading reports that provide consistency and accuracy based on science. They do not only provide reports, but they also educate clients on the characteristics of diamonds and direct them to the right jewelers.

HRD Labs

The High Diamond Council (HRD) is European based. HRD was founded in 1976, and it has since been considered one of the top global laboratories when it comes to accurate grading services in the European market according to Beyond4Cs.


Certification and Assurance Lab (GCAL) is an ISO 17025 forensic accreditation. With their ISO approval, GCAL conforms to international standards for accurate and reliable grading.

The above diamond grading organizations are stated as resources for informational purpose. There are vast resources on natural colored diamonds to the public. However, the President of Premier Diamond Group (North America) Ltd., Mr. David Metcalfe is available for consultation. He is a pioneer in the branding of natural colored diamonds as a hedge against excessive market volatility brought about by speculation and government credit excesses.
