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 specialising in high-end jewellery since the 1850s, recognised the need for a broad and well-founded knowledge of the gemstones it was mounting in its own items of jewellery. The laboratoryâ€™s standard of excellence and tireless devotion to the science of gemmology soon came to be rewarded with international esteem and recognition. Developments within the gemstone and jewellery industry over the past century have amplified the necessity and importance of our laboratory. We face the steady stream of challenges with determination and dedication, all the while pursuing the traditions of the Gubelin Gem Lab.
