A new mix here at the Rock Shed.  This mix contains a wide variety of stones at a reasonable price but be forewarned that these are also a wide variety of hardnesses.  It will make this mix more challenging to tumble, or you can separate it before you tumble.  The mix may include Rose Quartz, Zebra Jasper, Aventurine, White Quartz, Agate and others (Those are the hard ones).  It also may include Fluorite, Onyx, Orange Calcite, Sodalite and Fuschite (Those are the softer ones).  This material comes in sizes from 3/8″ to 1″.  It will also make a nice rock for fountains or other decorative uses.
