AGTA GTC's Koivula & Hughes Lecture in New Mexico
On August 29, 2005, the AGTA GTC's John Koivula and Richard Hughes lectured to attendees of the Radiation Effects in Insulators Conference in Santa Fe, New Mexico. Organized by Dr. Kurt Sickafus of Los Alamos National Laboratory, the evening lectures provided attendees with a double-barreled blast of both the internal and external worlds of gemology.
     Hughes began the evening by relating his own personal entry to gemology via a round-the-world sojourn he undertook at age 18, then jumping to the latest challenges facing the field today, including beryllium diffusion and the detection of heat treatment using UV fluorescence. He finished up with a moving personal account of his 1996 pilgrimage to Burma's Mogok Stone Tract, a place he continues to be drawn back to.

John Koivula then proceeded to bedazzle attendees with one stunning image after another illustrating the internal world of gemstones. Koivula, who is about to release Volumes 2 and 3 of his Photoatlas of Inclusions in Gemstones (in conjunction with the recently deceased Edward Gubelin), showed the attendees that, far from being "flaws," inclusions are not only visually attractive, but offer valuable clues regarding the origins of gems and, indeed, the earth itself.

Visit to the Los Alamos National Laboratory
In addition to their lectures, Koivula and Hughes were given a tour of the Material Sciences building at Los Alamos National Laboratory by Darrin Byler. They visited four different labs, including those involving particle acceleration, electron microscopy, crystal growth and mass spectroscopy.
     A number of excellent contacts and discussions resulted from this meeting and tour, the fruits of which will help keep the AGTA GTC at the forefront of the gemological field.
