GSI Lab to offer Sarine Profile with Diamond Grading Reports

June 2015 – GSI (Gemological Science International), one of the world’s largest gem labs, is pleased to announce that it has decided to incorporate into its polished diamond grading and education services the full Sarine ProfileTM, including deriving the stone’s light performance grade based on Sarine LightTM-measured data and providing the Sarine LoupeTM imaging and detailed Hearts and Arrows and 3-D Cut proportions graphic renditions. The joint collaboration between two of the industry’s most technologically advanced companies will offer many new possibilities to their wholesale and retail customer base.

GSI has expanded its global footprint in recent years to become one of the world’s largest gem labs, with offices in the U.S., India, Israel, Belgium, and Botswana. GSI provides gemstone identification, grading, and education services to many of the larger US retail chains, and combines state-of-the-art technology, being the only gem lab established in the 21st century, with deep professional expertise. As part of their mission to provide state-of-the-art services, GSI has opted to adopt the Sarine ProfileTM and utilize it for light performance measurement and analysis, imagery, and Cut quality graphic rendition. This cooperation between GSI and Sarine underscores a mutual commitment to excellence, as was evidenced by the early adoption of Sarine’s groundbreaking DiaMensionTM Axiom by GSI, and signals a new level of the relationship between the two companies.

Debbie Azar, GSI’s co-founder and Executive Vice President, stated that “Two fundamental pillars of our unique approach to our mission for the benefit of the industry are integrity and innovation. We have evaluated the Sarine ProfileTM and have compared it to the other systems available today, and are convinced it is a unique solution, which meets our criteria for technological leadership perfectly. We further believe that Sarine’s other current technologies, and those being developed, show potential for further cooperation between our two companies.”

Uzi Levami, Chief Executive Officer of Sarine, stated, “We are delighted that GSI has chosen to adopt our Sarine ProfileTM. Sarine’s industry-leading technologies are designed to advance the diamond industry, whether in the manufacturing midstream or the polished trade downstream to ever greater levels of quality and efficiency. We are confident that the envisioned cooperation will benefit both new and existing customers – logistically and commercially.” Mr. Levami further noted that “The business model agreed upon will add to Sarine’s growing recurring revenue base, in line with our long-term goals.”

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.
