For two weeks every winter, the world meets in Tucson as it becomes a bustling, international marketplace of buyers and sellers at the Tucson Gem, Mineral & Fossil Showcase.

The "Gem Show" is much more than a single event at one location.  Rather, there are thousands of participants and attendees at more than 40 sites around town.  Dozens of shows take place at the same time in different locations.

There's something for everyone at the many open-to-the-public shows - from gold and diamonds to granite bookends and glass beads, and from fine specimens of dinosaur fossils to opals dug from the Australian Outback.
