Madoc Rocks started in 2002, manufacturing hand made rock coasters with rock from the Madoc, Ontario area. The area is geologically on the edge of the Canadian Shield, where volcanic silicate rock meets sedimentary calcitic rock. The tectonic forces and chemical makeup of the area has been responsible for the incredible diversity of rock we have been able to access and use in Madoc Rocks products.
they are sold individually.
