As old as the province, Ontario’s Mace was made in Ottawa in 1867. It was fashioned out of copper and gold-plated. Sitting underneath the crown within decorative leaves, the cup of the current Mace features the insignia of King Edward VII. In 2009, the first two diamonds mined in Ontario were mounted into the crown of the Mace. One was left in the rough to represent the mining process, and the other was polished to signify the value of the diamond industry in Ontario.
