Kingston Conglomerate Copper
What a pretty stone this is, a mosaic of rich chestnut and shining copper. It comes from the Kingston Mine, located on the Keweenaw peninsula in the upper peninsula of Michigan. According to Mr. Jack Keck of Houghton, MI, who wrote in with firsthand information as he worked for the mining company, the mine itself has been closed since 1967, making the supply of this material limited. The metal gives each stone both beauty and heft.
