Tunduru River Rainbow Gems is a super cool mix of multiple gemstones that come from Africa.
This 1 gallon bag of gem gravel will have you searching for garnets, sapphires, rubies, spinels, chrysoberyl and zircon. These are not huge gems but some will be big enough to cut a small finished gemstone. They can also be kept as a collection where you can admire the fantastic colors. We had purchased this gem mix about 10 years ago and have searched for it ever since. Thankfully, we were finally able to get more of this colorful, gemmy material to share with you.

Rock Creek Sapphire Gravel 5 pack. Get 5 bags of the Rock Creek sapphire gravel from the Sapphire Mountains near Philipsburg, Montana. Each bag contains about 2 gallons of natural, unwashed, sapphire concentrate. This Montana sapphire gravel comes from the Potentate Mining Company.
This mountain material will contain a lot of clay. You'll also find small sticks, pine cones 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. This clarity helps make them easier to distinguish among the base material. A difficult material to work but tends to produce sapphires that respond well to heat-treating.
SORRY, NO GUARANTEES
