The following summaries are for conferences where Gemworld participated. Not all speakers are listed, only a partial with information from their talks. Canadian Gemmological Association Conference Vancouver, Canada October 16-18, 2015 This was a special celebration year for the CGA conference as it marked the 20th anniversary of the first conference in Vancouver (it was the 26th conference overall). Donna Hawrelko, president and conference chair, gave a moving tribute to the event as she was also the chair of the first conference held there. Speakers at this conference that also spoke at that first one 20 years ago included this author (RD), Alan Hodgkinson, and Gary Roskin. Gary Roskin opened the event with a lecture on communicating color. We are at crossroads as labs create names that promote color. As the color sells better, then the ranges get larger. He noted a sale of a “pigeon’s blood” ruby that sold for $50,000 per carat because of the report! He predicts that in the future we will see more reports with names that used to mean a place, now define a color. We know about Paraiba being used for other origins besides Brazil and he predicts it will happen with Kashmir and Ceylon for example, to describe a range of blue. The labs will continue to do this and resistance is futile. He urged consistent standards with defined ranges. Dr. Cigdem Lule discussed color nomenclature. Current trade terms and brand names may imply attributes not present. Species and groups are accepted by mineral groups and can take up to two years to get approval. Varietal names are different as the trade decides and there is no unified system. Dr. Lee Groat reviewed Canadian gems and diamonds. Canadian diamonds are now #4 in the world in carats produced and dollars per carat. Their global market share is expected to grow. Other gems being mined...
