E.G.L. - The European Gemological Laboratory: E.G.L. provides a detail diamond report that is sometimes not as strict as
G.I.A. Because the art of diamond grading is a subjective science, two different gemological laboratories may arrive at differing opinions when
assigning a diamonds color and clarity grade. E.G.L. has sometimes been known to assign a higher grade on diamonds that have grades on the border
between two grades.
G.I.A. usually will always give the lower grade. When purchasing a diamond with an E.G.L. quality report, it is possible to
receive a lower grade if it is submitted to G.I.A. for a new diamond quality report. Diamonds with E.G.L. quality reports that are offered for
prices significantly lower than equal quality G.I.A. certified diamonds have the greatest chance of not matching if submitted to G.I.A. for a new
quality report. E.G.L. certifications are often reliable but one must be aware of possible inconsistencies and limitations when comparing diamond
certifications between different gemological laboratories.
The E.G.L. certification however does provide more proportion information than the G.I.A. diamond report by including the
important pavilion and crown angles in their diamond report. Be aware that plots of internal and external blemishes on E.G.L. certifications are
much less detailed than G.I.A. or A.G.S. quality reports. Many diamonds under one carat in size are certified by E.G.L. due to the benefit of
lower cost and faster service. E.G.L. also provides a economically priced miniature version of its full certification.
