Diamond Certification

A "Certified Diamond" is a Diamond which has been evaluated for it's unique properties and endorsed with a guarantee of stated quality from an independent Gemological Laboratory.  A Diamond Certificate does Not establish a diamonds value, it simply helps in preventing fraud by allowing a consumer to have confidence in a purchase. Any Diamond can be "certified", regardless of size, quality or value.

There are many Diamond certification companies, each with a slightly different rating system.  Below is a list of the most popular certification laboratories in order of consistency and reliability:  Excellent, Very Good, Good, Fair & Poor.

Gemological Institute of America (GIA) Excellent
American Gem Society Laboratory (AGSL) Excellent
Stuller Red Box Diamond Certificate (SSI) Very Good

European Gemological Laboratory (EGL) Good
International Gemological Institute (IGI) Fair
NOTE:  Comparing Certifications from two different companies is like comparing Apples and Oranges.  A Certificate's purpose is to protect you from fraud.
