CHICAGOLAND GEMS & MINERALS ASSOCIATION
50th ANNUAL SHOW · May 29th & 30th 2027 ·

A Show by Rockhounds for Rockhounds!

For the love of rocks, the five Chicago area rock and mineral clubs of CGMA have come together to present one of the Midwest region’s largest shows for rockhounds.

Do not take it for granite, for this is no ordinary rock show. For two big days, the Expo Center of the Kane County Fairgrounds becomes a geological wonderland of fun for the entire family with more than 30 nationally known retail and wholesale dealers, fascinating exhibits by museums and private collectors, “blacklight” fluorescent mineral display, exciting silent auctions, great door prizes, and a Kids’ Korner of mighty learning and freebies for junior rockhounds. Shop for wondrous rocks, gems, minerals, crystals, fossils, handmade jewelry, strands of beads and pearls, tools and supplies, books, findings, slabs and cabs, and much more. See hands-on demonstrations of jewelry making, metal smithing, wire-wrapping, cabochon cutting, beading, geode cracking, and more.
