Is the IGI certificate as reliable as HRD or GIA certificate?

The International Gemological Institute, the world’s largest independent  
laboratory for testing and valuating gemstones and fine jewelry, was  
established in 1975 and is located in New York City, Antwerp, Toronto, Los  
Angeles, Bangkok, Mumbai (Bombay), Dubai and Tokyo. IGI can be reached at

The International Federation of Diamond Bourses in their 1978 report  
accepts IGI as an equal to the longer existing HRD or GIA.

Being a newcomer in those days (1975), IGI was being looked at with suspicion, and that is why - even nowadays - some people still refer to IGI as a lab too young to be good. Ironically, IGI today faces more discussions with  
dissatisfied diamond dealers than HRD  or GIA  does, for it is their  
feeling that IGI's grading system has become too severe, both for color  
as for clarity.

According to some diamond websites, the impression is given that GIA is  
the 'only' consistent grader: however, GIA's main share holder is Mr  
Robert Mouawad who is involved in many diamond companies. This has given  
some people in the diamond community more than once the feeling that a  
conflict of interest could arise from this potential mix of diamond selling  
with diamond grading. The recent GIA scandal in 2005 of diamond  
misgradings for some very large diamonds will do nothing to quell such  

Neither HRD, nor IGI houses share-holders that operate in commercial
diamond activities. This emphasizes their status of independence.

As for consistency of IGI grading:

./.. IGI Awarded Certification in Both the United States + Canada

NEW YORK – The International Gemological Institute (IGI) today announced  
its Los Angeles and Toronto labs were granted International Organization  
for Standardization (ISO) 9001:2000 certification for operating a quality  
management system in the scope of independent third party analysis of  
diamonds, colored gemstones and jewelry articles.

ISO is a network of national standards institutes from more than 140  
countries working in partnership with international organizations,  
governments, industry, business and consumer representatives to more  
directly link business objectives with business effectiveness.

ISO 9000 is a generic name given to a family of standards developed to  
provide a framework around which a quality management system can  
effectively be based. The ISO 9000 family of standards was revised in  
December 2000.

According to IGI North America President, Jerry Ehrenwald, G.G., A.S.A.,  
"This is a milestone for IGI. The ISO 9001 certification emphasizes the  
Institute’s continued commitment to provide clients with the highest  
quality of services available. It demonstrates that IGI is dedicated to  
excellence in every phase of its business operations."

To be certified to the standard, companies must implement a quality  
management system that accounts for a range of company activities,  
including staff training, meeting customer requirements and delivering  
services. This is done using Plan-Do-Check-Act principles and Process  
Management, which outlines the steps taken to provide customers the  
services pledged by the company.

As part of the ISO process, a third party auditor performed on-site  
assessments in both the Toronto and Los Angeles labs’ documented  
procedures, and audited its overall operations. To ensure continued  
compliance with ISO 9001:2000 and to provide feedback internally on  
process effectiveness, IGI business operations will be independently  
assessed by periodic routine surveillance audits.
GIA is an independent nonprofit organization established in 1931,
GIA (Gemological Institute of America) is recognized as the world’s foremost authority on diamonds, colored stones, and pearls.
GIA exists to protect all purchasers of gemstones, by providing the education, laboratory services, research, and instruments needed to accurately and objectively determine gemstone quality.
As creator of the 4Cs and the GIA International Diamond Grading System™, the Institute sets and maintains the standard for grading and identification practices used worldwide.
