German Foundation for<br />
Gemstone Research<br />
DSEF German Gem Lab<br />
Dr. Claudio Milisenda at<br />
the world’s largest ruby<br />
mine in Mozambique<br />
bile lab which can be used to test precious<br />
stones out and about, for example<br />
at trade fairs or abroad. It offers<br />
gemstone determination and authenticity<br />
testing, as well as diagnostic<br />
findings reports on the origin and possible<br />
artificial changes in the properties<br />
of coloured gemstones according<br />
to international standards, all using<br />
the very latest in testing techniques.<br />
Special analyses such as the diamond<br />
colour or the determination of pearls<br />
or cultured pearls are also possible. A<br />
team of geoscientists and experts<br />
from other scientific fields work together<br />
closely in a laboratory at the<br />
forefront of modern technology.<br />
Being located at the very heart of<br />
the German gemstone industry is an<br />
invaluable advantage, as those working<br />
at DSEF are the first anywhere in<br />
the world to analyse new discoveries<br />
in the world of gemstones, as well as<br />
new synthetic production methods,<br />
imitations and artificially enhanced<br />
gems. Thanks to its scientific contacts<br />
with the world’s leading precious<br />
stone-producing countries and a close<br />
working partnership with the trade<br />
market, the DSEF always has ‘the real<br />
deal’ on hand for comparison – its employees<br />
regularly undertake trips to<br />
the most important mines across the<br />
planet to collect originals. The results<br />
of their findings can regularly be found<br />
in different national and international<br />
magazines and are presented to experts<br />
in the field at different events.<br />
