For over 20 years the Annual Gem and Mineral Show held in July at the Carmichael Arena offers treasures and prizes to over 2000 attendants each year. A variety of dealers offer hand-made jewelry, beads and gems to the public on site throughout the weekend.

In addition a wide selection of exhibitors from the Canadian Museum of Nature, Laurentian University, University of Waterloo, Canadian Gemmological Association and Northern Ontario Relic and Treasure Hunters will offer rock displays, fossils, minerals, gems and more. Amateur metal sleuths can also interact with popular metal detecting displays and equipment.

Children are entertained at the Kids Corner where they can learn to make a rock collection or dress pebbles with funny faces. Demonstrations include silversmithing, soapstone carving, stained glass and the art of making arrowheads called "flint knapping"

The Sudbury Rock and Lapidary Society's 70 members have been organizing the Gem and Mineral Show for 13 years in Greater Sudbury.
