GSI Offers Digital Plotting

High-Tech Solution Brings Greater Report Accessibility, Accuracy and Security

Gemological Science International (GSI) announced today that it has added digital plotting to its list of proprietary, high-tech software applications for diamond grading. Digital plotting not only reduces paperwork and streamlines the grading process, it allows access to plotted diagrams and reports from anywhere in the world, said GSI president/CEO Mark Gershburg.

“We can now plot a diamond in our lab in Mumbai and print out the report in New York—or vice versa,” said Gershburg. “It gives us tremendous flexibility in addition to the benefits of more accurate plotting.” GSI also sees digital plotting as an important benefit for its growing number of e-commerce customers, who want to see the actual report with a plot without having to scan it.

GSI is the only major lab, other than GIA, that does digital plotting, according to Gershburg. He explained that in many other labs, graders plot the diamond by hand onto a diamond diagram, but the final hand copying onto the grading report is often not done by a gemologist. At GSI the grader plots the diamonds directly into the computerized diagram, and it shows up, exactly as plotted, on the final printed report. “This technology reduces human error that can occur when plotting is copied onto the report,” explained Gershburg.

With a report that is fully digitized, GSI can also easily replicate it in the event of loss or damage. “It used to be that only diamonds were ‘forever’; now we can say that our reports are also forever, because the plotting has been digitized and saved,” said Gershburg, whose goal is to take the lab business in the direction of a paperless office.

To that end GSI has developed a highly computerized and automated grading lab, where customers can view online their actual final grading report as soon as it is printed and track, Fed Ex-style, the status of their diamonds 24/7, among other innovations.

A full-service gem lab, GSI’s clients are mainly large manufacturers, major jewelry chains, department stores, and online jewelers. It is headquartered in New York City’s Diamond District at 581 Fifth Avenue and has an office in Mumbai, India. For more information, visit or call Debbie Azar at 212-207-4140 Ext. 202.

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.
