Show Co-Chair's Letter
Welcome to the 68th Tucson Gem and Mineral Show®, the culmination of the three weeks of mineral madness here in the Old Pueblo that have grown to legendary status worldwide.
This year TGMS is celebrating the many members of the Quartz Family through our “Agates and Opals and Quartz, Oh My!” theme. We expect Quartz is familiar to almost everyone since it, and its relatives, including Petrified Wood- Arizona’s State Fossil are everywhere. The basic building block of this family is SiO2-Silica, which is a key component of much of the earth’s crust and from which we derive essential daily products ranging from glass to the silicon chips in just about every electronic device we have.
The Tucson Gem and Mineral Show® is put on by a home-grown group of volunteer mineral enthusiasts many of whom collect Quartz-Family minerals and live to share our love of all minerals, rocks, fossils and Earth Science. This Show is our annual gift to Tucson and within you will find a unique world-class pop-up mineral museum that will exist for four days and vanish never to be seen again. You and your children would have to travel the world to see a fraction of the marvels we’ve brought you…and intend to keep bringing you for years to come! Waiting are dozens of exhibits of Quartz Family minerals plus other exotic and beautiful gems and minerals from many of the world’s preeminent natural history museums and private collections. So come on in and lose yourself in the varied colors and forms of Silica, learn why and how it became our State Fossil, ogle agates from Mexico, Opals from Australia and be sure to see the best collection of single Gem Crystals ever assembled!
TGMS is all about education so, in addition to the exhibits, there are lectures by professional mineralogists and hobbyists; booths in the Galleria where you can interact with mineral scientists, representatives of state and federal geological agencies and professional organizations to learn about available educational resources for the earth sciences. Or visit the Micromount Symposium and Activities Room where you can learn about the delights of using a microscope to appreciate the thousands of mineral species that only occur as tiny crystals. We are especially proud to feature exhibits by mineral-related winners of the annual Southern Arizona Regional Science Fair (SARSF) and of our Junior Education Program, run in conjunction with the SESS geology student group from the U of A, where children of all ages can learn about many aspects of our fascinating planet…with an emphasis on its minerals. Kids are challenged to learn, turned loose to apply their new learning in the exhibits area, and rewarded for their efforts by a starter collection that they have earned on their own.
You will also find mineral specimens, jewelry, gems, fossils and publications relating to them brought for sale by more than 250 of the world’s highest quality dealers, manufacturers and importers. There’s something for everyone…and the hunt is at least half the fun. In the process we hope you learn more about these fascinating products of our earth and a bit more about the community of mineral lovers who come here annually for this event…they all come for very good reasons…find out why!
We also hope you learn a bit more about the Tucson Gem and Mineral Society…we don’t “fold our tents and go home” after the Show…we ARE home and active ALL year, with monthly programs and member activities, and we provide funding for all levels of Earth Science education in our local schools and Universities. Stop by one of the Information Booths and pick up the literature about how to join and get involved with the Society and our Show…it can be YOUR Show too!
Watch out!! You might just also get bitten by the Mineral collecting bug!!!

2023 TGMS Show Co-Chair
Show Co-Chair's Letter
I know that many of you are as excited as I am about the coming of the Tucson phenomenon that happens every January and February, because I can feel the excitement in the air as dealers start moving into town from all over the world. For years, starting in my college days, I dreamt of coming to Tucson for the Show. I guess it had something to do with the fact that the first one was over my first birthday, way back in 1955. So, living here and being directly involved in this event is literally a dream-come-true!
But how many of you know how it all started?
It goes back to some members of TGMS attending a mineral show in the Phoenix area early that year. They came back and told the club “We should have a show.” Two to three weeks later, the very first Tucson Gem and Mineral Show© was held in the cafeteria of the Helen Keeling Elementary School. From the beginning, the focus was on education – introducing the public to the hobbies we all enjoy, as well as encouraging curiosity about the earth sciences in general. Over 1,300 folks attended that first Show over two days!
It became obvious that they needed a bigger venue, so the next Show was held at the Rodeo Grounds (now the Fair Grounds) and it continued to grow each year. In 1961, someone in the club had the “audacity” to invite the Smithsonian Institution to bring a display to the Show. At that time, the Smithsonian didn’t take anything anywhere. But Paul Desautels, Curator of the mineral collection, was intrigued. After asking where Tucson was, he used the “It’s easier to get forgiveness than permission” approach and brought a display to our Show. The 2020 Show was the 60th consecutive year they displayed, a record interrupted by the COVID-19 pandemic.
Having the Smithsonian as a partner in our educational efforts became a big draw, and the Show began to attract many more museums and institutions, creating the most phenomenal exhibit of mineralogy, lapidary, and related topics anywhere.
As our Show continued to grow, and eventually moved into the Tucson Community Center, Satellite shows sprang up – now over 40 different shows occur in January and February, but the Tucson Gem and Mineral Show© remains unique in that it is not a commercial show, but is run by staff and volunteers. It is also unique in the proportion of floor space dedicated to educational exhibits.
Education is still the reason we do it! Sure, there are dealers at our Show. I thank them at every opportunity for partnering with us. They help us finance this “one-of-a-kind” exhibition. We would not be able to do it without them! Many of them have told me over the years that they enjoy the “different” atmosphere at our Show. It has an ambience not found at the many other shows they attend. They appreciate the friendliness and helpful nature of the many volunteers. They appreciate the opportunity to view world-class exhibits from leading national and international museums and institutions – it gives them something to look at during their breaks, besides their competitors. And they appreciate the broad spectrum of people attending and participating in the Show, from young children to seasoned academic scientists.
So if you are here at the Show reading this, you are participating in one of the truly unique events in the world. Each year history is made here, young (an old) minds are turned on to the hobby. Some of those going to become the exhibitors and world-class dealers of tomorrow. But many more get to spend one to four days absorbing the wonders presented here.
Thank you for being a part of this!

On behalf of the Tucson Gem and Mineral Society, welcome to our 68th annual Show, “Silica - Agates & Opals & Quartz, Oh My!.” I look forward to seeing all the friendly faces and wonderful displays that makes this the best mineral and gem show in the world! I am a native Tucsonan and it is such a pleasure to have this Show in our city every year.
The theme this year will have some exciting displays with all sorts of beautiful cases and exhibits featuring some fantastic mineral specimens and gorgeous jewelry. The staff, club members and volunteers put many hours in planning, and work on this Show year-round to bring our visitors this wonderful Show.
The Tucson Gem and Mineral Show® is unique in its educational emphasis, attracting novice collectors, to academic researchers. It is the largest of its kind put on by volunteers, and the only one in its class sponsored by a loc al non-profit club that you could join! Look for membership opportunities on our website (www.tgms.org) or at the information booths in the Exhibit Hall or Galleria. Seventy-six years ago (December 3, 1946), a couple dozen collectors met to form TGMS. In March 1955, two weeks after visiting a Phoenix show, members put together their own in a school auditorium. As it grew, and eventually moved to the Tucson Community Center, others began to see opportunities, and satellite shows appeared.
In 1961 a member audaciously invited the Smithsonian Institute to bring a display. At the time, the Smithsonian didn’t take anything anywhere, but Mineral Collection Curator, Paul Desautels was intrigued, and convinced his superiors to try it. Every year since, the Smithsonian has partnered with us, displaying many priceless national treasures. Such partnerships with other museums contribute to the uniqueness of our Show. Whatever your interests, I know you will find an abundance of exhibits and merchandise to enjoy.
Visit our Junior Education Area (west end of the Galleria) and see how our partnership with the University of Arizona, Society of Earth Science Students (SESS) is influencing new generations with the collecting bug. There will be several free lectures on a variety of topics at all levels, so please make time in your day to catch one of these. If you need assistance, please look for a docent wearing a green vest that can answer questions or direct you to someone who can. When the urge comes, grab a snack or drink and meet other collectors or dealers in the food-court.
Thank you for coming. We hope you have had such a great time that you will return year-after-year. There is nothing else in the world quite like the Tucson Gem and Mineral Show®, and I hope you will go a step further and join TGMS so you can add your talents and dedication to future shows.
