Columbus Rock and Mineral Society

Hello and thank you for visiting the Columbus Rock and Mineral Society website.  

As President, I would like to express my joy in participating in such an active club.  Each year we put on a wonderful Rock, Gem and Jewelry show along with our partners from the Licking County Rock and Mineral Society.  With last year's show success at our new Location at the Northland Performing Arts Center, we are happy to be at the same facility again this year.
Ohio has such a rich history, but also an incredible pre-history.  With this year's show theme of Frozen: Ohio's Ice Age, we want to show a slice of what Ohio was like back when it was covered with ice and snow.
Also, Ohio is also celebrating 50 years of flint being the states official gemstone.  To help in the celebration we have several displays of flint and also the show's grand prize will consist of some one-of -a-kind flint items.
If you enjoy Rocks, Fossils and Minerals as much as we do, then I encourage you to join us for a club meeting to see what we are all about. 
John Helwig
CRMS President
