I am still trying to hydrate after returning from San Diego via the southwest, but I wanted to share some tourmaline related highlights.
1, My spectrometer’s light source will be modified to be better able to analyze color.
2, A lead rich Achroite may have been discovered during testing at the Washington University in St Louis. And there is interest in testing more tourmaline.
3, The GIA will be photographing 50 of my best tourmalines for a potential human interest story in their magazine Gems and Gemology.
4, The GIA has accepted my last two pieces of rough Laurellite (cuprian, reverse color change tourmaline from Mozambique) for possible testing to more completely understand this unique tourmaline.
5, I am not a heater, but I will be helping to prepare a significant lot of darker, mostly blue green tourmaline to be heated. I hope that some smaller pieces may be suitable to cut unheated. It is Brazilian and would be a bit different for the collection.
