Geoscience Industries is a privately owned U.S. Company that has been manufacturing quality earth science products for almost 35 Years. Our products are sold by many of the major educational catalogues and our product line of gift and rock shop kits are sold worldwide. As you will see on the website, our products include many configurations of rock, mineral, and fossil collections, sized samples of rock and minerals, individual fossil specimens, and display mineral specimens. All of these items are manufactured/assembled by us in the USA. GSI is a wholesale manufacturer and therefore we do not sell to the retail market. If you would like to sell our products please see our Terms and Conditions of Sale page.
