Gems & Minerals

"The Tucson Gem & Mineral Show is produced by the Tucson Gem and Mineral Society. This show has been held annually since 1955 and now occupies 181,000 square feet (16,800 m2) of the Tucson Convention Center. Many museums and universities, such as the Smithsonian Institution and the Sorbonne have displayed here. The rock shows that occur in a two week period bring in over $110 million to the local Tucson economy."

Yes, I contributed to the Tucson economy today. Not a lot.
I have collected rocks and fossils since I was a child. There is something magical about the things that occur in nature.
I continue to be fascinated...
