The Tucson Gem Show

It has been called “The Greatest Treasure Hunt in the World”, and the city of Tucson, Arizona is invaded annually by its participants.

“It” is the Tucson Gem, Mineral & Fossil Showcase — the largest event of its kind in the world. From its start as a one-weekend show put on by a local club (the Tucson Gem & Mineral Society), The Tucson Show (as it is commonly called) has grown to encompass more than 40 separate gem, fossil, and mineral shows located at venues ranging across the entire city of Tucson. It has become so important to the City of Tucson that the City Manager’s Office created a position for a TGMS Liaison Officer.

This map of Tucson (produced by Interweave Press, who publish The Tucson Show Guide), marks the locations of the 42 separate events which comprise the Tucson Gem, Mineral & Fossil Showcase.

Many of the shows are open to the public, although there are a few, such as AGTA (American Gem Trade Association) and GJX (Gem and Jewelry Exchange) which require proof that you are a wholesale buyer in the gem and jewelry business. One year, as I was standing in line at GJX to get my badge, I overheard a woman trying to get in with a reseller license for an interior design business – she was turned away.

The AGTA (American Gem Trade Association) show is held in the Tucson Convention Center. It is one of my favorites because it not only has stunning gems, it also features exhibits from the Smithsonian, displays of award-winning  jewelry, and educational seminars. It is also much less claustrophobic than some of the other shows, where one can hardly move without bumping into another person.

I spend most of my time hunched over tables like this, searching for the gems which will inspire my jewelry designs.

It is difficult to imagine the scope and range of this event unless you have experienced it. From cheap tchotchkes to rare minerals to the most magnificent gemstones and jewelry, The Tucson Show has it all. As someone before me has said, if it’s not at Tucson, it probably hasn’t been discovered yet.

It is not just designated event venues that host the various gem shows. Any open space will be taken over, either by RVs where dealers just park and set out their wares on a table or by tents (some simple pop-ups, some that are hundreds of feet in length, complete with air-conditioning). If a show is located at a hotel, not only is every public space in the hotel given over to vendors, but the rooms themselves become stalls.

The photos below were taken at this years’ 22nd Street Show, one of the event-tent venues.

To a meteor collector, this a little piece of heaven.
