Pioneers in gemmological education

The science of gemmology can trace its origins back to 1908 in Great Britain. The decision to create a medium for professional gemmological education resulted in the establishment of the Gemmological Association and Gem Testing Laboratory of Great Britain, recently renamed to Gem A (www.gem-a.info). The tremendous experience gained from identification and evaluation of the British crown jewels, in addition to the fact that London is the distribution center of 60% of the world’s rough diamond production, contributed in the first gemmological diploma in 1913. The above two reasons, combined with the traditional and sometimes tough British education, resulted in a gemmological diploma whose holders are described as the “elite” of gemmologists.
