It was quite an amazing revelation when I first heard of Sylvia Gumpesberger's work on gemstone magnetism. Sylvia is one of those gemology pioneers who open up new horizons in gemology, and then drag the rest of the industry kicking and screaming into new concepts and new technology. The following year I was honored to have Dr. Don Hoover visit our booth at the AGTA Gemfair in Tucson (yes, we used to be members before Tibet andesine issues) where he demonstrated the separation of garnets based on magnetism. When you think about it, the iron content of many gemstones is sufficient to create a magnetic attraction, and this was the basis for the reports.
