More About Gemlab
The Gemological Appraisal Laboratory of America has become a staple to New York City’s Diamond District since its inception in 1979.
Kenneth A. Lejman, of GAL, built the company from the ground up.
As one of the leading appraisal companies within the United States, GAL has provided appraisal reports to not only the jewelry industry and consumer market, but has also provided services to federal government organizations such as: US Customs, Department of the Navy, FDIC, and the District Attorney’s office.
GAL holds accreditations through the National Association of Jewelry Appraisers, as well as being active members with the GIA Alumni Association, including Charter member status.
In recent years, Gemological Appraisal Laboratory of America has transitioned to new ownership, where Travis Lejman, the son of Kenneth, has taken over operations with his business partner, Joshua Lents. And in the last 5 years, they have joined a very small minority of appraisal companies in the United States that is equipped with much more advanced instruments that are typically only found in state-of-the-art laboratories and Universities. This has allowed GAL to take their business to the next level and conduct much more sophisticated analysis on colored stones and diamonds, furthering their capabilities and ensuring precision accuracy. In 2013, GAL was invited to become part of a brand new organization of independent, analytical laboratories throughout the world, called the “International Consortium of Gem-Testing Laboratories” (ICGL.) Made up of independently owned laboratories spanning 5 continents, this prestigious network of over a dozen laboratories has introduced a new concept for researchers and lab specialists that allows for open communication among colleagues while fostering a better understanding of new discoveries in the field of research and analysis.
The staff at GAL is made up of industry veterans, each possessing between 10-30 years of gemstone and jewelry experience, and offering individual expertise that collectively covers nearly every facet of the industry.
All gemologists carry a minimum G.G. (Graduate Gemologist,) as well as some members of their staff having completed their Fellowship (FGA) through the Gemological Association of Great Britain.
GemLab’s appraisals and lab reports are recognized and respected worldwide by retailers, jewelers, wholesalers, insurance companies, and law enforcement – and by consumers just like you, who need the most accurate and reliable appraisal available in the industry.
Gemstone Identification Report
Gemstone Identification Reports are requested for standard identification and verification of diamonds and colored stones. This report will include the species of the material, detailed measurements, quality, weight, along with a detailed photograph of the gemstone in questions.
Gemstone Identification w/ Origin Report
Everything included in the Gemstone Identification Report, with the addition of the region of geographic origination. Tests are conducted to determine where the material was formed and mined from. (Ceylon, Burma, Brazil…etc.)
Diamond Grading Report
A diamond report will cover all four C’s: cut, color, clarity, and carat weight. In depth measurements of the proportions are noted, along with a detailed mapping of the inclusions, which will give a complete visual of the internal characteristics, which is useful for identification purposes.
Pearl Grading Report
Pearls are unique and have a completely different set of grading parameters, compared to a diamond or colored stone. Details that are only specific to pearls, such as: luster, overtone, and surface characteristics are key points which influence the value of pearls.
A Sarin report is an incredibly detailed listing of individual facet, depth, and table measurements and angles, all required when planning and re-cutting a diamond, customizing a mounting to very strict parameters, or determining ideal proportions, such as “Hearts & Arrows.”
Identification of Treatment(s)
With technology rapidly advancing everyday, the likelihood of undisclosed treatments which enhance the appearance of a gemstone occurs more frequently than ever before. This is a significant factor when evaluating or buying a gemstone at the right price. A natural, untreated blue sapphire is much rarer and more valuable than a blue sapphire with a similar appearance that has been treated.
