GSI Opens Lab in India Offering More Options to Clients

Tracking & Other Tools - GSI Opens Lab in India Offering More Options to ClientsGemological Science International, headquartered in New York’s Diamond District, announced today that it has opened an office in Mumbai, India. The lab is fully owned by GSI and is located in the Opera House area. 

“We’ve been working in Mumbai for the past three months, learning about the market and determining the best location to open our lab,” said Mark Gershburg, President/CEO of GSI. “In addition to the Opera House lab, we also have the capability of going right to our jewelry manufacturing clients in SEEPZ and anywhere else through our Mobilab™. This mobility gives us incredible flexibility to serve the industry, when and where they need it. It also saves a lot of time,” added Gershburg. SEEPZ is the duty-free area in Mumbai, where jewelry for export is manufactured. 

“We bring to Mumbai the same high level of customer service and technological expertise as we have in New York,” said Gershburg. This includes the flexibility of being able to print grading reports either in India or New York—no matter where grading is done—and the ability to Gemex diamonds and print joint GSI/Gemex reports. Equipment for GSI Mumbai came from the U.S. and from India. 

At this stage GSI Mumbai is staffed with a senior gemologist from GSI’s New York office and local graders with GGs who have had experience serving the American market. “We have full control of the lab in Mumbai because all the work is channeled through and monitored by our staff in New York via our proprietary software,” said Gershburg. “This ensures that all requirements for a client’s particular program are fulfilled.” 

The new GSI lab, which is open for business, is located in the Platinum Arcade, Ground Floor, 96/93, J.S.S. Road, Opera House, Mumbai 400004. For more information contact Debbie Azar, Executive VP, in New York City at 212-207-4140 Ext. 202

GSI markets its gemological grading services (ggs) mainly to large manufacturers, major jewelry chains, department stores, and online jewelers. It is headquartered at 581 Fifth Avenue, Fourth Floor, New York, NY 10017.

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

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 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.

  • Rotating gemologists to our different labs
  • Continuously upgrading our proprietary grading software to ensure full compliance with international grading standards
