There are various gem laboratories out there providing their own independent judgments on gemstone specifications. Unfortunately, often these laboratories vary in their strictness in grading of the gemstones. One has to be skeptical in particular when the lab providing the certification is the same lab selling the item, as there is a conflict of interest. For this reason, all of GemsNY gemstones over $1000 in value come with independent lab certifications. Below we list and provide details on only the most respected and well known laboratories:

 
 

UGL - Universal Gemological Laboratory

UGL is located in New York City in the jewelry district. Their strength is to provide detailed appraisals and certificates for gemstone jewelry. They have been in business for over 15years. UGL is the only lab which uses a standard grading system for emerald, ruby and sapphires. Also unlike GIA, which is the largest lab in the world for diamonds and gemstone certification, they provide both certificates and appraisals using their proprietary grading system.


 

GIA - Gemological Institute of America

GIA is the largest and most reputable lab in the world. There is no lab in USA which is even a close second in terms of certification for gemstones and diamonds. Only drawback with GIA is that they don’t provide appraisals for loose gemstone or finished jewelry.


 

GRS - Gem Research Swisslab

GRS is also one of the leading gemstone grading laboratories and is one of the most commonly used labs for gemstone jewelry and loose gemstones. In Asia and Europe, the two of the most prominent labs are GIA and GRS for gemstone certification.


 

TGL - Tokyo Gem Laboratory Co., Ltd.:

TGL is also a leading gemstone grading laboratories and is also used very commonly in the jewelry trade around the world. This laboratory has various branches all around the world. This is one of the labs GemsNY prefers.


 

EGL - European Gemological Laboratory:

EGL gemstone certificates are used occasionally in the trade. This lab is known more for diamonds certifications than gemstones.


 

IGI- International Gemological Institute

IGI is used heavily by large retailers such as Macys. IGI again is a second tier lab used for diamond grading primarily and their grading are definitely much more lenient then GIA.
