Many in the diamond industry consider GIA the gold standard of diamond graders.GIA grading reports have been considered to be a hallmark of integrity throughout the diamond world.Established in 1931, the not-for-profit GIA has its headquarters in Carlsbad, California and has a presence in a number of locations worldwide.

• Number 1 and most respected.
• You can be sure any diamond with GIA certification has reliable and consistent grading.
• 3 – 6 gemologists grade a diamond separately to ensure accuracy.
• GIA issues two kinds of reports:
• GIA Document – contains full description of the diamond and a plotting of the clarity characteristics of the stone. Generally done for sizes above 1 carat.
• GIA Dossier – contains the full description of the diamond. However, plotting is replaced by a laser inscription that can be used for verification. Generally done for smaller stones.

IGI grades diamonds and gemstones from its headquarters in New York and several other U.S. locations.

• Provides a detailed certification that is not as strict as GIA
• Provides more information than the GIA Report including pavilion & crown angles
• Typically used by diamond cutters for smaller diamonds
• Reports cost lesser than GIA and therefore diamonds graded by IGI can be priced lesser than an equal grade of GIA
• Grades would vary if resubmitted to GIA. Grade Variations however are rarely more than 1 grade

Founded in 1978, the AGSL is based in Las Vegas, Nevada.

• Known throughout the diamond industry for grading top-notch round ideal cut diamonds
• High standards surpass that of any other grading laboratory in the world
• AGS Ideal Cut Diamond is highly sought after

There are a few independently owned grading labs that carry the EGL name. EGL-US certificates. EGL-US has been independently owned since 1986, and is based in New York.

• Officially represents the Belgian diamond sector at home and abroad
• Enjoys an excellent reputation for objectivity & quality
• Established in 1973, based in Antwerp
• Objectivity guaranteed by maintaining strictest anonymity
• When the diamonds are bought to the lab, the data is inputted in the computer and the stone is given 2 numbers – one printed on the receipt note and one for internal follow-up. The grader therefore can never trace whom the stone belongs to.

D for diamonds and G for gems .... The name itself indicates that we are exporters and importers of loose and polished diamonds for more than TWO DECADES.....
