The 49th Annual CGMA Show will be held May 23rd and 24th, 2026 at the Expo Center of the Kane County Fairgrounds.

Hello again! We’re thrilled to announce that the Chicagoland Gems & Minerals Association will be hosting our amazing 2026 show over the Memorial Day weekend—mark your calendars for May 23 and 24! This is truly an event you won’t want to miss—a rock show created by rockhounds, for rockhounds. For details, check us out at https://cgmashow.com/.

This year is especially exciting, as we are also honored to host the annual conventions of the Midwest Federation of Mineralogical and Geological Societies and the American Federation of Mineralogical Societies during the show.
