The sweet scent of herbs rises above the finely carved brown bowl during a smudging ceremony as it cleanses the home of negative energies. Catlinite, a soft stone called argillite or metamorphosed mudstone, was traditionally quarried in Minnesota and Canada to be carved into pipes, smudge bowls, and beads. It is also called catlinite pipestone or pipeclay. The reddish-brown or black stone is the traditional material for Native American peace pipes. The Minnesota quarry, located in Pipestone National Monument, allows only registered tribal members to mine for catlinite. Catlinite deposits in the Southwestern states, such as Utah and Arizona, contain a harder form of the stone that is difficult to carve with a knife. Whether seeking a traditional catlinite peace pipe, beads, or carving materials, reliable sellers on eBay provide a wide variety of products and craft materials, with detailed descriptions of each item. The convenient shipping options allow buyers to select the best method of receiving new or vintage catlinite pipestone pieces.
