GRS is honoured and proud to welcome you to our Fourth Issue of Contributions to Gemology. We have named this the “Summary Edition’ which compiles almost 5 years of research on the topic of Beryllium-Treatment of Corundum. This continues our tradition on working and striving to share knowledge, research and detailed information concerning the exciting field of modern gemology. In this Summary Edition, we have compiled our previously published research which also includes the results from the co-operation with world-recognized Universities and internationally respected Research Institutes.

GRS strives to continue it’s in depth research utilizing sophisticated scientific methods. We have invested significant resources in research and development. This includes for example the invention of a new type of Laser Induced Plasma Spectrometer (LIPS) using a UV Laser. This technology is the answer to a non-destructive test to detect Beryllium-Treated corundum. Its calibration is based upon solid scientific research using sophisticated instruments which produced a masterpiece set of unique standards. The collection of this data and standards are summarized in this 4th Issue of Contribution to Gemology. We are convinced that this Edition is a landmark in the world of research on Beryllium-Treated corundum. We, at GRS, believe that international acceptance can be achieved through information and knowledge that is shared with the world.

Thank you and please enjoy our topic-related “Summary Edition” of GRS’s Contribution to Gemology.
