The Tucson Gem show was started by two couples: Dan and Betty Caudle and Clayton and Betty Gibson. The first gem show was held in 1955 in the Helen Keeling Elementary School Cafeteria. For the next 17 years the show was held in Quonset huts and livestock buildings at the old Pima County Fairgrounds (now the rodeo grounds) on South Sixth Avenue. Since the Tucson convention center was built in 1971 the show has been held there.
