Certified Natural Gemstone

Whenever you are buying an expensive Natural Gemstone, make sure that you get a certificate from a reliable lab along with it! This ensures that you are getting what you paid for. At peakgems.com, Natural gemstones that are beyond US$300 will be certified by either the Gemological Institute of America or the International Gemological Institute.

Gemological Institute of America (GIA)

Established in 1931, GIA is the world's most respected nonprofit institute of gemological research and learning. Internationally, the Institute has distinguished itself as the preeminent source of gemological knowledge and professionalism. The Institute's scientists, diamond graders, and educators are regarded as the world's foremost authorities in gemology.

International Gemological Institute (IGI)

Established in 1975, IGI is the largest independent gemological laboratory worldwide. It is controlled by one central governing body, which ensures consistency in IGI reports across the globe. In adhering to the one internationally accepted system for grading, IGI offers its clients a peace of mind.
Today, IGI issues more than one million reports per year.

What is in a Gemstone Certificate?

It shows the characteristics of the gemstone including whether it is truly a Natural mineral. Other measures include the species, variety, weight, shape, cut, clarity and dimension of the gemstone. Some certificates may also include its origin. Another important part to look into is the "comments" section which may indicate if any "treatments" were applied to the gemstone.
