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.
