This gorgeous stone is a combination of rich chestnut color and shining copper. It comes from the Kingston Mine located on the Keweenaw peninsula in the upper peninsula of Michigan. The mine itself has been closed since 1967, making the supply of this material very limited. The metal gives each stone both extraordinary beauty and weight. -WET pic.- 2"x 2"/1.6 oz./5+mm thk) end cut no fractures...great cutter
