Ottawa — the Largest Rock N’ Gem Show is back this fall. This October, vendors from across Canada will gather in Ottawa with crystals, minerals, fossils, gemstones, jewelry, beads, carvings, lapidary supplies, handcrafted creations, and thousands of unique treasures for visitors to explore.
For four exciting days, the Cohere Centre will be transformed into a marketplace filled with natural beauty, creativity, and discovery. Visitors can browse everything from sparkling crystal displays and rare mineral specimens to fossils, polished stones, handcrafted jewelry, décor pieces, and collector favorites.
One of the highlights of the Rock N’ Gem Show is the incredible variety of vendors who take part in the event. Many are passionate collectors, artisans, miners, lapidary artists, and family-run businesses who enjoy sharing their knowledge, stories, and love for the world of rocks and gemstones.
