A Destination for Exceptional Fossils and Minerals

Formerly known as the Main Avenue Fossil & Mineral Show, the Madagascar Import SEAM Gem Show has evolved into a unique destination, now solely occupying this historic Tucson property. Established in 1994 in Antananarivo, Madagascar, SEAM began by specializing in exporting Madagascar’s renowned ammonites, which are celebrated globally for their remarkable quality. Over the years, SEAM has expanded its offerings. SEAM now exports a diverse range of premium minerals and fossils to collectors and enthusiasts worldwide, with a strong presence in the U.S., Europe, and Asia.
