Although missing from the name of the Tucson Gem and Mineral Show (TGMS), the descriptive modifier "international" would fit quite nicely.
When I asked one person in the amythest geode display if the geodes had come from the southwestern past of the country, he answered--after asking me to repeat the question talking more slowly--"Uruguay."
At another display area, I asked about these carvings and, if I understood the person, these jade figures are produced from Cambodian jade.
We came across some onyx tables made from dozens of 3-inch cubes glued together. They were large enough to seat four for dining. We also saw square onyx columns from four to six-feet tall with bulbs in the columns. They were the type of floor lamp that would serve as the center of attention in a room. Because they were such artistic creations, the owners of the Sedona (AZ) company asked that we not photograph them.
At the end of a corridor in the Center, we came upon hundreds of these beautiful stones (shown in the three photos below).
The photographs of the cabachon (below) and rings (second photo below) don't do justice to the actual items. Onnik's matching of the precious metal with the colors of the quartz produced stunning items.
