The pipe handled cane below has a handle made from a carved meerschaum pipe ($5.00 at the thrift store).  It is supported by a brass candle stick cup.  Meerschaum is a soft clay like mineral from Turkey.

The globe on the other cane is from China and is a mosaic of different colored minerals and brass set in plastic (another gem show buy) mounted with a brass screw and candle stick cup.
