Virgin sapphire gravel that has been enriched with many various gems. Perfect family entertainment for rock-hounds and treasure hunters. Gravel may contain gold flake and fossils as well as natural Montana sapphire.

Virgin, unwashed gravel from the Rock Creek sapphire deposit.  This material is not from the Gem Mountain commercial mine but from the Potentate Mining Company.   This sapphire gravel comes packaged in a 2 gallon sack. The material will contain a lot of clay as well as sticks, pinecones and debris making it very difficult to wash clean.  Hopefully your added time and effort will be worth it. Fortunately, when you do get it clean, the Rock Creek sapphires are usually quite gemmy, making them easier to distinguish among the base material.  A difficult material to work but tends to produce sapphires that respond well to heat-treating.  Complete washing instructions with photo are included to assist you through the process.

Complete gem mining package that is educational as well as providing great entertainment for family time, birthdays, reunions or anytime.
