About Us


We have four annual shows located throughout Arizona, and even one in Colorado. We have a showroom in Tucson, AZ open year-round (by appointment). We look forward to seeing you soon.

JG&M Expo

JG&M Expo is our annual show so large it takes place in three physical locations in two States! Between our two shows in Tucson, Arizona approximately 100 different vendors from around the world gather to exhibit their specimens. Our Simpson Street Show open to both the general public and to wholesalers, while our Michigan Street Show is primarily wholesale (wholesalers, please remember to bring your TAX ID). Starting in 2012 we also have a show in Denver, CO! For more details visit our website where you can find our show schedule, our hours of operation, and even print out floor plans before you visit!

Gemstone Material Interiors

Gemstone Material Interiors is our spectacular showroom. We’re open to everyone as part of the Main Avenue Gem Show, or year-round by appointment. Come by if you’re looking for something beautiful or unique, or perhaps even specimens so large you can only find them here.

Prospectors Panorama

Prospectors Panorama is our annual show that is worth going out of your way for. It is our longest lasting annual show yet, running from early January until mid February. Here, we have our very own MUSEUM. Yes, you read correctly. Our museum is unique in that everything is for sale!! If you thought the the Tucson Gem Show was impressive, you must experience the show in Quartzsite, AZ for yourself.
