Everyone at CGMA is busy getting ready for our 42nd Annual Show, A Galaxy of Gems. We want to thank all of our wonderful dealers, our returning customers, and the many new people who came to our new, bigger, facility, Kane County Fair Grounds, St. Charles, IL. The 2018 show will feature special displays, demonstrations, a daily Silent Auction, and a special Kids Korner. The dealers will have jewelry, minerals, fossils, and gems from around the world.
