A short history of J.J. & L. Rocks and Minerals





Our motto is



J.J. & L. Rocks and Minerals was started 36 years ago by Jim, John, and Larry, three friends in the rock hobby who each had a specialty.  One was into minerals and faceted stones, one into select cutting rough and supplies for the hobby, and one into findings and jewelry.  The three men combined their specialties and created a gem and mineral business, taking it on the show circuit in the Midwest area.  After a slow start of doing one show in Nebraska the first year and three shows the second year, the business was off and running.  The shop has been doing 16 to 23 shows each year ever since, with occasional weekends having two shows in different towns.  The shop has traveled to Idaho, Colorado, Wyoming, Kansas, Oklahoma, Texas, Missouri, Illinois, Minnesota, South Dakota, Wisconsin, and Nebraska.  The local shop is open by appointment only, please contact us by e-mail  jimandjohn@jjlrocksandminerals.com for an appointment time.



Larry left the partnership after about 10 years, but remained friends with John and Jim until his untimely death.  John passed in 2013.  Eric is John's youngest son who has grown up under the tables at the show is now interested in continuing the rock shop along with Jim. 


Thanks for the support of our shop and hobby.
