The 2020 Tucson Gem and Mineral Show® Introduction

Our annual show reports of the happenings at Tucson will start with the 2020 Tucson Gem and Mineral Show®. This show is the main show that started all the other mineral and gemstone venues in Tucson and made it the mecca it is today for mineral and gemstone collectors.

This first post introduces the Tucson Gem and Mineral Show®, showing some of the general show themes, as well as some of the major cases, including the largest Gold specimen found in modern times, an iconic wire Gold that serves as the logo for the Harvard Mineralogical Museum, and the famous "Snail" Rhodochrosite specimen from South Africa, that was one of the most expensive minerals ever sold. This was also the 50th anniversary of the Mineralogical Record, with several cases highlighting this milestone.

We will also create additional posts for several of the other Tucson shows. For the Tucson Gem and Mineral Show®, we'll add posts on the exhibit cases, individual minerals, and dealer minerals. 

This page will contain links to all the posts that we create as we organize and publish them. Stay tuned and check back frequently for additional updates on Tucson, including posts on the exhibit cases, individual minerals, dealer minerals, and other shows in Tucson.

The 2020 Tucson Gem and Mineral Show® Displays Part 1

This post about the 2020 Tucson Gem and Mineral Show® focuses on some of the amazing displays at the show. Private collectors, dealers, museums, and mineral clubs set up public display exhibits that showcase some of the most exceptional minerals that are out there. 

This show, the most prominent mineral event in the world, features over one hundred displays with a wide variety of specimens that rival the displays of the best museums in the world. It would be difficult to cover these displays our post, so we chose some of the most prominent and photogenic samples and divided the display exhibits into two posts, this being the first one.

This year's theme was "World Class Minerals." This is a loosely defined terminology and this is a more encompassing theme than in previous years. The website of the Tucson Gem & Mineral Society devoted a page to explain the theme - visit their website to read more about the theme at http://www.tgms.org/news-archive/2019/10/20/world-class-minerals.

The 2020 Tucson Gem and Mineral Show® Displays Part 2

This is our second post on the display exhibits of the The 2020 Tucson Gem and Mineral Show®. We divided the photos of the displays into two posts to keep it from being too long. We didn't put these photos in any particular order -- the order is the sequence of our photographs.


In past years, we separated our posts on the display cases into separate posts for theme-related and non-theme related. However, with this year's more ambiguous theme of "World Class Minerals," every case seemed to have been filled with "World Class Minerals" so it was hard to separate the theme from the non-themed. We therefore included them all together and did not designate separate posts for this.

Please stay tuned for our next post which will include some of the exceptional minerals within these display cases.

The 2020 Tucson Gem and Mineral Show® Display Minerals Part 1

This post shares some of the individual minerals on display in the exhibits at the The 2020 Tucson Gem and Mineral Show®. As always, the minerals were outstanding, with an abundance of old classics, new finds, amazing aesthetics, and great rarities.


Of the hundreds of great minerals we photographed in the exhibits, this selection is a condensed version narrowing down our top picks. This decision of which minerals to include in the post is always a difficult one, and proved even harder this year than in previous years because we didn't separate the posts by theme vs. non-theme minerals. This year's theme of "World Class Minerals" really left all the exhibit minerals liable to fit under the theme definition, so we didn't differentiate between the themed minerals and non-themed minerals as was done in our show reports from previous years.


This is the first of two posts on the individual show minerals. Stay tuned for our next posts on the individual minerals which we will be posting shortly.

The 2020 Tucson Gem and Mineral Show® Display Minerals Part 2

This is our second post on the individual minerals of the Tucson Gem and Mineral Show® display Minerals. A continuation of our previous post, this post shares some of the remarkable minerals on display in the exhibits at the show.

There were so many good minerals on display, and it was difficult having to choose the best ones. However, we are posting many of the other great display minerals we photographed at the show on our Instagram page at instagram.com/mineralsnet, so please check there as well for additional show minerals.

Our order of the pictures does not follow any system. We simply posted in the order of how we photographed them at at the show. We hope you enjoy!
