The Gem Shop, Inc. specializes in fine agates and jaspers. The types of specimens represented below are for sale and organized by rock type. Most are polished, but some are not. Outstanding examples of other agates and jaspers in private collections, which are not for sale can be seen in the Gallery. If you are interested in the sources for some of these rocks and some of our mining adventures, you may want to visit our mining pages.
All sales are on a first-come, first-served basis. Our stock changes frequently so be sure to check back for updates and new merchandise.
