Where is Gemological Science International (GSI) located?

GSI is headquartered in New York, NY. It has 13 laboratories on four continents and in a number of countries: the United States, India, Dubai, Israel, Belgium, Hong Kong, and Botswana. This makes GSI one of the largest independent gemological organizations in the world.

Is there a difference between grading reports issued by different GSI laboratories?

All GSI laboratories grade using the same methods and adhere to the same standards. Every laboratory is staffed with highly trained professionals who have years of grading experience and an extensive gemological background.

What does it mean when a sales associate tells me my diamond is “GSI Certified” or is accompanied by a “GSI Certificate”?

The phrases “GSI Certificate” and “GSI Certified” are industry shorthand for GSI grading or identification reports. What this means to you is that expert gemologists and trained professionals meticulously evaluated the item. When your diamond, jewelry or gemstone is accompanied by a GSI grading report, you can be completely confident in the accuracy and objectivity of the evaluation.

Where can I find “GSI Certified Diamonds”?

GSI diamond grading and identification reports can be found in jewelry stores worldwide and online. Insist on a GSI grading report when shopping for a diamond, jewelry or gemstone.

What do I do if I lose my GSI Diamond Report?

Every GSI grading report is available on our website. Please visit and go to “verify your report”. Enter your GSI report number and you’ll instantly have access to a digital copy of it. You can also email us through the website to request a copy.

What are the 4Cs

A beautiful diamond is one of nature’s most mesmerizing creations. But how do you objectively judge the quality of the gem? The 4Cs – Cut, Color, Clarity, and Carat Weight – are the universal standard for doing this.

Is there anything beyond the 4Cs?

The 4Cs are an essential and important description of a diamond’s characteristics. But there is a considerable amount of detailed information behind each “C” along with other qualities of a diamond that affect its beauty, such as fluorescence, light performance and more.

How much do you need to know? That’s up to you, but knowing the 4Cs is almost essential.

What does a GSI diamond grading report look like?

GSI offers a number of grading reports (often referred to as “GSI Certificates”). You can see samples of them by browsing the Grading Reports page on our website.

What does a GSI colored diamond grading report look like?

How does a GSI grading report compare to other laboratories that issue grading reports?

  • Rotating gemologists to our different labs
  • Continuously upgrading our proprietary grading software to ensure full compliance with international grading standards
  • Having our gemological research department constantly investigate new developments in the industry, which informs the grading process

What’s the difference between a “GSI Certificate” and a “GSI Diamond Grading Report”?
