Diamond & Jewelry Certification
A diamond certificate, also known as a diamond grading report, is an easily understood document prepared by an expert gemologist that describes the key characteristics of a diamond. A certificate from a gemological laboratory verifies the quality of a loose diamond and allows non-experts to make educated diamond buying decisions.
GIA Diamond Certification
Founded in 1931, the Gemological Institute of America, or GIA, is an independent, non-profit organization considered by many to be the world's foremost authority in gemology. Introduced in 1953, their diamond and gemstone grading system is recognized worldwide. Manufacturers from around the world send diamonds and gems to GIA for examination and analysis.
When a diamond is accompanied by a GIA certificate, the consumer is assured that the stone has been analyzed by an unbiased gemologist who upholds the highest standards of integrity, science, and professionalism.
IGI Diamond Certification
Established in 1975, the International Gemological Institute, or IGI, is the largest independent gemological laboratory in the world, with locations in all major diamond centers. IGI's mission is to provide jewelry professionals and consumers with extensive education programs and reliable diamond and fine jewelry certification.
An IGI certificate is comprised of a detailed analysis of a diamond's characteristics by several expert gemologists.
