| Gary Roskin's "Evening with the Blues" presentation at AGTA GemFair |
Gary Roskin, one of the world’s leading gemologists as well as a longtime educator and writer, was one of 10 gem experts who examined and photographed the Hope and Wittelsbach-Graff diamonds—the most famous blue diamonds in the world—to determine whether their origins were the same.
The event took place Jan. 21, 2010, inside the “Blue Room” (the outer-room of the gems and minerals vault) of the Smithsonian National Museum of Natural History. Roskin documented the event and has been writing about it on his website, the Roskin Gem News Report, in series titled, “An Evening with the Blues.” More recently, he brought this story to life during a presentation at AGTA GemFair Tucson. Below are seven video excerpts from that presentation.
