Gem Gravel

12 bags of the Rock Creek sapphire gravel.  Each bag contains 2 gallons of virgin, concentrated Montana sapphire gravel from the Potentate Mining Company.  The material will contain a lot of clay making it difficult to wash clean.  Fortunately, when clean, the Rock Creek sapphires are usually quite gemmy, making them somewhat easy to spot.  A difficult material to work but tends to produce sapphires that respond well to heat-treating.  Instructions with photo are included to assist you through the process.  Sorry, NO GUARANTEES.
