Gubelin :

The origins of the Gubelin Gem Lab go back to the early part of the 19th century. In the 1920s, the Gubelin Company, a firm that had been specializing in high-end jewellery since the 1850s, recognized the need for a broad and well-founded knowledge of the gemstones it was mounting in its own items of jewellery. The laboratory’s standard of excellence and tireless devotion to the science of gemology soon came to be rewarded with international esteem and recognition.

Since new technologies are continually being developed and applied to alter and treat rubies, sapphires, emeralds and other gemstones, the IGI scientific approach is vital to ensure optimum reliability.

The IGI Colored Stone Report clearly states whether the stone is natural or synthetic, provides other data describing its shape, cut, weight, measurements, color, transparency and major optical characteristics, and also includes a detailed photograph of the stone. The country of origin is stated on the report if the gemological analysis conclusively reveals it.

Gemstones should only change hands when accompanied by a certificate attesting to quality. Regardless of location or marketplace, an authentic IGI Laboratory Report is the common language of trust and confidence in the gemological world.

Founded in 1977, and located in the heart of New York's gem and jewelry district, American Gemological Laboratories (AGL) is an international gemstone testing facility specializing in comprehensive colored gemstone analysis. AGL provides detailed identification and enhancement reports, country-of-origin reports, as well as complete colored stone analysis documents tailored to gems of unique importance.

AGL is a pioneer in the colored gemstone industry and was the first gemological laboratory in the USA to issue country-of-origin reports. Additionally, we were the first in the world to quantify colored stone quality in a clear and comparative manner. In addition to our position of leadership in gemstone documentation, AGL has extensive experience in consumer protection programs.

The Laboratory is equipped with state-of-the-art instrumentation, and applies standard gemological, as well as advanced analytical, techniques to each determination it makes. Building on our cornerstones of meticulous characterization and disclosure, AGL has a long tradition of acquiring staff who are experts in the field of gemstone testing and reporting.

In 2009, AGL was purchased and re-privatized by Christopher P. Smith, who had been Vice President and Chief Gemologist of the laboratory while under Collector's Universe ownership.

AGL and Christopher Smith are members of the International Colored Stone Association (ICA) and the American Gem Trade Association (AGTA). Since early 2007, AGL has significantly expanded its work and collaboration with other industry, government and research organizations to promote a broader familiarity, better understanding and proper representation of gemstones and gem materials.
