ABSTRACT
First he examined the interactions between the lingering effects of the COVID-19 pandemic and current economic and social transformations. In light of the session in his honour, Dr George Harlow (American Museum of Natural History, New York, USA) chronicled the history of his career, in which he built collections, organised exhibitions and performed geological fieldwork around the world while researching jade, ruby, etc. Pamir rubies formed at unusually low pressures (minimum of 1–1.2 kbar) and a temperature of approximately 760°C. Wim Vertriest (Gemological Institute of America [GIA], Bangkok, Thailand) and co-authors reviewed the identification of low-temperature heat treatment of gem corundum (i.e. up to about 1200°C, which starts causing damage to rutile ‘silk’ inclusions). In another presentation, Dr Dutrow and co-authors investigated the origin determination of Cu-bearing tourmaline using statistical analyses of LIBS and electron microprobe data.
ABSTRACT
Gem-A Conference, Graduation and Presentation of Awards In the first week of November 2021, Gem-A hosted two significant events for its Members and Students, signalling a return to some in-person events and the continuation of Gem-A’s annual conference tradition. The conference was followed by the Gem-A Graduation Ceremony and Presentation of Awards on the evening of Monday 8 November, hosted at Church House in London, where participants enjoyed balcony views across Westminster Abbey. Gem-A has long reserved the first weekend in November to host its most anticipated annual events, including the Gem-A Conference, field trips to the Natural History Museum and Tower of London, and its annual Graduation Ceremony and Presentation of Awards. ‘COVID-19 restrictions did force us to make changes in our annual in-person events, but we are reintroducing the Gem-A Conference and Graduation Ceremony in ways that are safe, effective and for the benefit of our Members and Students,’ explained Alan Hart FGA DGA, chief executive officer of Gem-A.
