GIA Certified Diamonds

GIA is dedicated to safeguarding the interests of gemstone buyers and sellers by establishing and upholding the criteria used to assess the quality of gemstones.

The institute accomplishes this through extensive research, providing gem identification and diamond grading services, and offering a wide range of educational programs. With an extensive library and a team of experts, GIA serves as a valuable source of information on gems and jewelry for the industry.

In 1953, GIA introduced the groundbreaking International Diamond Grading System, along with the renowned “four Cs” (cut, clarity, color, and carat weight), as a universal standard for comparing and evaluating diamond quality.

EGL Certified Diamonds

EGL, the European Gemological Laboratory, made waves in the industry when they introduced the SI3 clarity grade. Initially intended to encompass diamonds on the borderline between SI2 and I1, it has now become synonymous with I1 diamonds that are nearly “eye clean.”

This means that the diamonds have inclusions that are not readily visible to the naked eye. However, the use of the same terminology by both GIA and EGL, combined with their differing application of grading standards, can easily lead to confusion or misinterpretation for diamond buyers.

It is not uncommon for a diamond to receive significantly different grades when submitted to both laboratories.
