Description
This workshop concentrates on treatment and origin determination of gemstones commonly encountered in the laboratory. Samples are tested with standard equipment, and the possibilities and limitations of the standard tools are discussed. The workshop will not only cover the “big three, ruby- sapphire- emerald”, but also spinel, Paraiba tourmaline, alexandrite and demantoid garnet.
Dr Lore Kiefert (Gemological Consultancy, Heidelberg, Germany) has worked at SSEF, AGTA and Gubelin labs as chief gemmologist and co-authored numerous gemmological publications in gemmological and scientific journals.
