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.

Our Rock Creek Sapphire Treasure bag is guaranteed to bring you success when sapphire hunting! About a half gallon of natural Montana sapphire gravel enhanced with heat-treated Rock Creek sapphires from gem mountain in Philipsburg, Montana. Gorgeous colors ranging from yellows to the deep Montana blue. Gem mining instructions are included. A little throwback to our Smokin' Hot Blues!
The base for this material is a virgin sapphire dirt but from a lower producing area - so you always have a chance to find a natural sapphire besides the gems we add.
