Each authentic stone used in Tumbled Earth has been collected from the shores of the Kootenay River in British Columbia. The stones were formed by glaciers approximately 22,000 years ago and naturally tumbled by the water. We do not use a man-made tumbler.
Next we use a hand drill and with precision and a special technique, drill the tiny holes in the stones. The stones are then slightly polished with petroleum jelly to give it that bright wet appearance. The stones absorb the polish and are not left greasy or wet.
